How to choose oil for boat engines. Types of oils for boat motors and their features, differences in the tacity of the motor and manufacturers Motor oil for suspended motors

The reviews of the shipowners say that correctly selected oil provides a boat motor for a long life and protects it when working in dirty or salty water, during operation in winter strumbs and in summer heat.

We offer to buy engine oil for 2 and 4 tactical boat engine

In order for the engine of your boat engine uninterrupted and the resource of his work remained the greatest, we offer buy Motor Oilwhich will provide:

• high-quality lubricant
• clean the details
• light Start of the Cold Engine,
• stable work With a wide range of temperature conditions,

Our store sells oil specially created for boat motors. It is enriched with additive complex for better operation of the propulsion on the water. When choosing an oil, it is worth considering its clue - the characteristics of the oil for two and four-stratified boat motors vary.

The price of a boat engine oil directly depends on the number of additives in it, and even on the mineral, synthetic or semi-synthetic basis it has.

Also you can also buy transmission oilwhich will ensure reliable lubrication of rubbing surfaces, reduce their wear and significantly will explize the service life. We offer transmission oil, the price of which depends on the class of viscosity and quality lubricantas well as from the presence of necessary additives.

A series of transmission oils for boat engines from various manufacturers is designed for the conditions of use on water, so the oil serves not only for lubricating gears and shafts, and also protects parts from corrosion.

Suspended boat motors have in their design nodes, some details of which are subject to wear as a result of friction. One of these nodes in the engine is a gearbox. To protect against wear of rubbing steam, a special is used.

Any grease during operation reduces its protective functions, so it is subject to replacement at a certain time. The oil replacement in the gearbox of the suspended boat engine can be made from the dealer. The procedure for changing the oil in the gearbox is simple, but requiring compliance with certain rules. Therefore, many motor owners produce a replacement of oil in the PLM gearbox independently.

How to choose oil for a boat motor gearbox

The feature of the operation of the motors is such that the screw reducer works under water. The engine itself together with the gearbox has a water cooling system. That is, inside the engine along special channels circulates water, which comes from the reservoir and cools the parts heating from friction.

Despite the protection of the internal parts of the gearbox from the water with rubber glands and bushings, inevitably entering the water inevitably. Water, salt in seawater create a destructive environment for rubbing nodes, rust appears, corrosion.

Motor manufacturers recommend applying for gearbox special oilsHaving in its composition additives binding water. Anti-emulsion additives confront the formation of emulsion, but their ability is not limitless. With a large volume of water, they will certainly not cope.

In oil, anti-corrosion additives may also be present, which do not allow rust and corrosion. Special effect they have during the operation of motors on the sea in salted water.

Transmis Zion oils used in gears and gearbox gearboxes do not have a set of anti-corrosion and anti-immulsional additives that bind water and protecting rubbing pairs from oil starvation. Applying their manufacturers of boat engines are not recommended. The benefit from the low cost can turn into expensive repairs of the gearbox.

The viscosity of transmission oils, which ensures reliable operation of boat motor gearboxes, must comply with the SAE 80W-90 class. Stationary boat motors require oil with a viscosity of SAE 85W-90.

According to the API standards, transmission oils for boat engine gearboxes must correspond to the GL-4 or GL-5 class.

API GL-4 Standard Oils Designed for lubricating conical and hypoid gears, which have a slight displacement of axes operating in variables in gravity conditions - from light to heavy. Usually it contains half the volume of additives used for oils of a higher class API GL-5.

Oil API GL-5 Used for more loaded hypoid gears having a significant displacement of gear axes operating in severe conditions.

In this way, oil API. GL-5 have a greater number of additives, provide the best anti-facility properties, protect the rubbing surfaces under conditions of blows, high loads and pressures. That is, the GL-5 API oils completely overlaps the requirements of the API GL-4 standard.

Which oil is used for a boat motor gearbox

Oil according to SAE and API standards, which must be poured into a motor gearbox indicated by the manufacturer in the passport on the PM. In addition, for each engine brand recommended oil of a specific manufacturer.

Yamaha Motor Oil

Protection during the operation of the gearbox at high speeds, from corrosion, rust provides a set of additives contained in the oil. They provide long service life of motors. Oil film on the surface of rubbing knots steady to oxidation and high temperatures. Oil excludes deposits near seals, does not form foam.

Tohatsu Motor Oil

Tohatsu does not prefer some oil producer. In its motors gearboxes, you can pour oil of any manufacturer that meets the requirements of the API GL-5, SAE 80W-90.

Mercury Motor Oil

Mercury recommends for its motors exclusively oil Quicksilver, in the line of which 3 groups of transmission oils. PREMIUM oil is used for all types of gearboxes suspended motors With a capacity of up to 75 hp and corresponds to the SAE 80W-90 class.

Stationary MerCruiser engines, suspended motors with a power exceeding 75 hp, require High Performance oil. Mix these oils with each other forbidden. Oils contain a unique package of additives that reduce the appearance of emulsion when water gets into the gearbox.

How much oil in a boat motor gearbox

Engines different power Manufacturers differ from each other and gearbox design. The higher the power, the more loads are experiencing the details of the gearbox. Since the dimensions of the gearbox increase with the power of the motor, then a greater volume of lubricant is required accordingly.

For example, for filling the oil into the tohatsu gearboxes up to 6 hp Requires up to 200 ml. Oils, up to 18 hp - 370 ml, 25, 30 hp - 430 ml, 40, 50 hp 500 ml, over 70 hp 900 ml already needed. Volume necessary oil Other manufacturers may differ slightly.

How to check the oil in a boat engine gearbox

To check the oil in the gearbox:

• we put the motor vertically on the stand or transom;
• we find on the left side of the gearbox the upper (control) hole, unscrew the cork;
• we insert the diploma into the hole, take it out, you can use a conventional match as a probe;
• if the probe is dry, pour oil.

How to replace the oil in a boat engine gearbox

To replace the oil, you will need:

• the container where it is necessary to drain the spent oil;
• wide slotted screwdriver;
• pads for traffic jams;
• special pump for pumping the oil of large volume if the volume of small oil is poured directly through the nozzle in the tube;
• new transmission oil;
• stand under the suspension boat motor, if the motor is not installed on the trans.

Sequencing

• We install the motor on the stand with the vertical location of the Deadwood. If the motor is installed on the translate, then the deydwood is also installed in a vertical position. Motor must be installed, slightly raising over the surface.
• Under the motor install the container For the drain of spent oil.
• We unscrew the bottom drain plug. The oil will begin to merge into the drain tank.
• We unscrew the top cork. We are waiting for the oil completely stalking from the gearbox (10 minutes). ATTENTION! Some "masters" after the oil drain recommend rinse with gasoline gearbox. In no case cannot be done. Gasoline destroys the glands, after which the water falls into the gearbox, forming an emulsion.
• Change gaskets on traffic jams (While the exhaust oil flows).
• Pour the freshly acquired oil into the gearbox. For refueling of small volume oil, special tubes (bottles) are used, which have a nozzle tightly inserted into the drain hole. If the volume is large, then apply special pumps. We insert the nozzle to the lower drain hole.
• Oil pouring stop under the condition that oil began to flow out of the upper test hole, And it is little without air bubbles.
• Holding the tube (pump) tighten the top cork.
• As soon as possible to minimize the loss of oil we remove the tube (pump) from the lower drain hole and tighten the drain plug. A certain part of the oil will still flow. If the volume is small, it is not worth worrying.
• Check oil level, By revealing the top control hole. If there are a lot of oils, it is necessary to add it. Low oil level can lead to the output of the gearbox.
• Tighten the plugs tightly. I wipe the oil from the gearbox. Exhaust oil transfer to special enterprises for further disposal.

Gradually fill more progressive 4-stroke devices. However, the overwhelming majority of swimming facilities are equipped with an old sample equipment. 2-stroke engines do not lose their popularity. Maintaining it in the working condition is the task of the engine owner.

So that the equipment is operated for a long time and efficiently, you need to choose correctly. For obvious reasons, many fishermen and hunters want to reduce their expenses. Therefore, they are looking for a replacement for licensed tools from the manufacturer of the motor. How not to make a mistake in the choice will help to understand the advice of experts.

Features lubricant

Engine 2-stroke Most often used for inflatable boats that are used by fishermen or hunters. This system needs proper care. The cost of the engine is high enough. Therefore, maintenance is necessary, taking into account all the requirements of the manufacturer. This will significantly extend the service life of the motor. For it, it is necessary to use special means. After all, the motor has a cooling system that applies not air, but water.

It has a simple device. It is compact enough, light. Such equipment quickly gains momentum and less demanding on fuel quality. A distinctive feature of such equipment is its lubrication with a mixture of oil and gasoline. When the engine is running, this composition combines inside the unit.

Requirements and standards

For 2-stroke, plastic media engines have TC-W3 marking. This standard has developed the National Association of US shipbuilders. It shows how well the tool lubricates, protects parts and engine mechanisms.

Oils must perform a number of mandatory functions. They prevent friction between moving elements of mechanisms. This increases the service life of the motor. In addition, the oil presented by the presented category allows you to reduce the aggressive impact of the environment (sea or fresh water) on the engine elements. Also high-quality lubricants are removed from the moving elements of the system.

The main requirement that puts the TC-W3 standard to lubricating products for 2-stroke engines is the absence of metal in them. This gives a guarantee that the components of the mechanisms will not be left from the mixture of oil and gasoline.

The base of the oil

Studying what oil for a 2-stroke motor Better to purchase, the owner of the swimming agent first should look into the instruction manual for this equipment. Manufacturers recommend certain types lubricantswhich fully comply with the design features of technology. If you plan to pour another oil inside the motor, you should purchase a means with an identical set of qualities, as well as used flushing for the unit.

There are two main types of oils for boat engines. Their base is made of synthetic or mineral components. The first option is more fluid. It is more often used in new engines. Mineral varieties are cheaper. They are often used in the engines of the old sample. Such formulations allow you to avoid leakage. Synthetic agents are easily seeping through loosely adjacent seals.

Additional components

In addition to the basics of B. oil for a 2-stroke motorit includes a certain number of additional elements. Their essentials are lubricating functions and the possibility of dissolving oil in gasoline. Most of these funds contain additives from polyisobutylene.

This substance is like its essence on rubber. When burning it in large quantities on the inner surfaces of the camera remains a nagar. Therefore, manufacturers create special formulas that allow you to keep the engine clean for a long time.

New technologies

Apply boat motor "Suzuki", "Mercury", etc.,the owner must choose proper tool. It must comply with or exceed the requirements of the international standard. For this, manufacturers use special technologies when creating their products.

Since additives are combined in various proportions, it is impossible to use other brand oil in the motor. Before it is necessary to thoroughly rinse the system with special means. But it is best to purchase the means of the same manufacturer of an identical brand.

When operating a motor in water, it is required to create conditions for this process as high quality. Temperatures at which the lubricant is burning around, in boat motors are much less than in the automotive. Therefore, some companies are developing additives that allow this process as high quality as possible.

Extension of life

Boat motor "Suzuki", "Yamaha", "Mercury" and many other popular devices are tested by the manufacturer in production conditions. In accordance with constructive features The equipment is developed by lubricating compounds, the most corresponding to the device of each boiler motor.

Large manufacturers of presented equipment create special meanswhich are most suitable for the manufacturing equipment.

In addition to high-quality lubricating and anti-wear functions, such means allow you to significantly extend the life of the motor. They reduce the formation of corrosion and ensure efficient burnout of lubrication components.

Evolution of oils

To choose correctly oil for a 2-stroke motorIt is necessary to evaluate the equipment itself. It can be quite ancient or new sample.

Previously, one type of oils was used for boat engines. It was called M-12-TP. Over time, imported varieties of products were imported into the country. Their analogue of the domestic sample was the MHD-14M product.

However, as expert advice suggests, today it can be considered good oil For suspended motors, only the one that has passed certification TC-W3. For the engines of the new sample should not be used other means.

In old engines, it is quite acceptable to apply mineral oil Old sample, such as MS-20. But such experiments with new engines are extremely not recommended. Modern synthetic tools significantly exceed the requirements of standards, therefore are considered in this case most preferred.

What to pay attention to when choosing?

Choosing oil for boat engines 2-stroke "Mercury", "Yamaha" and other new varieties of equipment, you should pay attention to some features. As already mentioned above, in this case it fits more synthetic lubricant. It passed the corresponding certification, was tested by manufacturers in special conditions.

In order not to make a mistake in the choice, you need to pay attention to the packaging. If it is written on "Synthetics" (Synthetic), most likely, in the jar there is a means of similar in its properties on mineral species. It has improved characteristics. But such lubricants do not correspond in their properties to the present synthetic oil.

To purchase lubricants on a synthetic basis, you should choose products with the inscription on the packaging Full Synthetic. When using such funds, the number of exhaust decreases, the biodegradability of lubricants increases.

Some shipowners choose oil for 2-clock boat engines, based on either someone else's experience, or on their own. Both are not suitable. To listen to the advice of experienced friends, of course, you need, but the manufacturer recommends that the manufacturer recommends. There is much more sadly the situation when the owner of the vessel transfers the experience of handling ... by car.

Despite the ever-growing prices, choose oil for push-pull boat engines is needed correctly. And for this you need to have a clear idea of \u200b\u200bwhat it happens. As you know, all options presented in the market are divided into two large groups:

• synthetic;
• mineral.

What should the representative of one preference? More expensive branded or ordinary, but cheaper? Let's try to figure out.

What is different from "Synthetic"?

The main difference between them lies in the material that is their basis. If mineral oil for two-stroke engines Boat engines are created on the basis of, roughly speaking, oil, the synthetic is obtained from specially obtained components. The latter are all sorts of:

• alcohols;
• esters;
• olefin polymers.

Experts recommend carefully reading all those present on the inscription packaging. If "synthetic" is bangible here, then it speaks only about the presence of a synthetic basis. In addition, such inscriptions are characteristic of companies using marketing to attract new customers. Simply put, we are talking about "mineral milk" with improved lubricant properties.

The presence of "Full Synthetic" inscription is almost a 100% synthetic basis guarantee. True, unscrupulous manufacturers can notice here "mineral water", thereby increasing the number harmful emissions and reducing the value of biodegradability.

What preferred?

So, in all this manifold, the inexperienced boat owner is lost and is not able to understand what oil is pouring into a boat engine. And all because such people just inatimately read the manual for the operation of the aggregate. As a rule, the manufacturer of equipment always indicates that you need to "pour" into the engine.

Very often, the TC-W3 standard is mentioned in the recommendations. If other explanations in the documentation are not given, you can use mineral varieties that comply with this standard. In addition, the manufacturer must be more or less well known and trust. This is ideal.

If you are interested in oil for a gearbox of a boat engine one of modern models (As a rule, these are powerful injection machines), then besides the options listed in the manual, it is impossible to use anything else! Since the SLM was created in the calculation on the "Synthetic", then it should only "go" it.

Is it possible to take transmission oil on a synthetic basis and pour into the usual "two-strokemother"? Yes, it can be done. At the same time, such an act does not hurt such an act. Rather, on the contrary. It should not be thought that mineral worse and will not allow equipment to work 100% the resource laid in it. No worse and, of course, will allow. Just the cost of its acquisition will be much lower.

Varieties and prices

One of the most famous in the market (both domestic and world) is oil for Yamaha motors. As you know, the manufacturer is very careful about its customers, and therefore developed a special line of lubricants under the Yamalube brand.

For example, 2M Two Stroke Semi-Synthetic for outboards worth 360-400 rubles per liter will provide the ideal operation of the engine operated in harsh conditions. This oil brand guarantees protection against corrosion / wear and provides ideal lubricant properties.

Yamalube oil

Another famous brand - Motul. Products offered to the Russian consumer are compatible with any lubricant: like separate, so with mixed. The additives used prevent the formation of scale and reduce the clocking of candles and the formation of a car. One of the main benefits of production is the ability of operational formation of emulsion (stable) during the compound process, that is, mixing, with gasoline. Both unleaded and eaten.

Typical representative - Motul Outboard Tech 2t. Its cost in Moscow stores is about 700 rubles.

Motul oil Outboard Tech 2T.

To the one who prefers the trademark Kvixiell, it is known that the oils offered by it are suitable for any PLM. However, there are some differences:

• premium category - can be used for motors with a capacity of at least 2.5 and no more than 115 "horses", with the exception of Optimax from Mercury;
• category Premium Plus - with any force aggregates;
• DFI - with devices having a direct injection system.

For example, the PREMIUM TC-W3 litter bottle produced in the US will cost approximately 800 rubles.

PREMIUM TC-W3 OIL

Are suzuki motor oil? Then you can buy Marine Ultimate 2T. TC-W3, whose manufacturer is Nippon Oil. Price Litona plastic canister It is about 520-530 rubles. When using this lubricant, it is necessary to comply with the proportions that are listed in the user manual!

MARINE ULTIMATE 2T oil. TC-W3.

As you can see, oil for 2-clock boat engines in Russian stores is presented in a wide range. Moreover, the cost is quite acceptable if you consider the importance of the PLM for the boat and its owner. Of course, trust deserves products from official manufacturers.

Some experts are convinced that in very short time oil for four-stroke boat engine (and only it!) Will be in demand by Russian shipowners. But statistics convinces us in the opposite: "Two-Points", firstly, more numerous; Secondly, the demand for them is only grown every year.

Each owner of a boat engine knows that right choice Oils are already 90% of the guarantee that thousands of tens (or even hundreds) spent thousands of rubles will serve "long and happily", and they will not go on scrap metal at the end of the season. In principle, the situation similar engine Any car - but with the difference that in boat engines due to the features of operation requires its special oil. It mainly concerns two-stroke engines but this will be discussed below.

What is the difference of oils for boat engines

Normal mode of operation car motor - 2000-4000 revolutions per minute. Before the peak power in 5000-6000 revolutions, it is rarely "spinning" - but for a boat engine is a normal mode, as it works in a more dense medium, respectively, the motor load is also much more than that of the car. And the last - elevated humidity, which is destructive for mechanisms.

In this case, it is impossible to forget that the oil for two-stroke and four-stroke motors is radically different. In two-stroke engines, the lubrication of moving parts inside the motor occurs due to the supply of fuel-oil-air mixture directly into the combustion chamber, so oil is added to gasoline, together with which he burns. Therefore, such oil must be in addition to the proper viscosity and lubricating properties to have a reduced smoke - remember what happens when the oil is in the combustion chamber of the conventional car motor?

For four-stroke motors, the lubricant of moving parts occurs as in the usual automotive engines. But at the same time, tighter requirements mentioned above the reasons mentioned above: higher revisions, an aggressive environment and so on.

The choice is very large: in addition to the manufacturers of these engines that offer corporate oil For their technology, lubricants make other companies. According to each manufacturer, its products are better than the products of competitors. Let's try to figure out how the situation is actually.

Oil for two-stroke engines

As mentioned above, it is used special. To date, all lubricants for such engines comply with the international TC-W3 standard - this is defined condition. The certificate of conformity is assigned to oil after it will be held a series of tests and tests according to the standards adopted by the National Association of US shipbuilders.

Therefore, all engine oil for 2-stroke motors is created by one standard. 60% of the product is oil base Middle viscosity (usually mineral), from 5 to 17% - residual clarified oil. 15-20% of the product - a solvent that allows oil as it can be mixed with gasoline and at the same time is an activator.

Everything else, that is, from 3 to 20% is a variety of additives that have a very wide range of functions. They allow you to reduce the smoke of the working mixture, control the lubricating properties, improve the solubility of the oil in fuel mixes, Protect against corrosion and remove the remnants of burning out. At the same time, each manufacturer focuses on one-two main aspects and therefore adds certain additives to its products in more than others.

• Oil - to reduce the amount of nagar, so there is a much greater percentage of residual clarified oil. This allows you to hold the soot in suspension and effectively withdraw it together with the residues of combustion products outside, through the outlet system.
• In the suspended motors, a more efficient cooling system and a residual moisture can get into the combustion chamber. Therefore B. Suzuki. Anti-corrosion additives add to oil to increase the service life of the motor.
• In oils Mercury. Additives are designed to provide effective lubricant moving parts of the motor and at the same time the maximum dissolution of the oil, which will reduce the smoke to a minimum and achieve compliance environmental norms. It is the smoke that is the main problem of two-stroke engines, which is why they are prohibited in a number of countries.
• The well-known manufacturer of lubricants produces mainly oil for high-mounted boat motors famous brands. Additive additives provide rapid mixing and low ash capacity of the working mixture.
• andNissan. For its Motors TLDI use oils on a synthetic basis. Such oils can be used for old carburetor engines These manufacturers are cheaper and not inferior to mineral in their qualities.
• Bombardier. Also uses partly synthetic oils With a crawling carbex that binds particles of ash and soot in the working mixture and effectively displacing them from the combustion chamber.

As can be seen from the above, the choice of oil is a matter of personal preferences. It is clear one thing - it costs a good good and a quality product cannot. Although the branded oil will cost an order of magnitude more expensive than the Yamalube is not inferior to him.

Oil for four-stroke engines

With everything is somewhat simpler, because by your design such a motor is completely identical to the car. The lubricant in it works on a closed cycle, and the main problem is the protection of the motor from overheating, opposition to the destructive effect of corrosion and a decrease in the nagaro formation. In fact, such oil is practically no different from what is used in vehicles - but with additives that prevent the appearance of an emulsion with water, provide protection against moisture and salt, and also better output fuel combustion products.

Transmission oil for gearboxes PLM

In addition to motor oilIn the suspended boat engines, oil is still used for gearbox. In this case, without a difference, what cliff has a motor - such a lubricant is suitable for any clue. It contains various additives that do not reduce wear of rubber parts, but also prevent the appearance of an aqueous emulsion, improve oil adhesion and prevent corrosion.

Despite all this, it is recommended to change each season due to the fact that the PLM is the high probability of water from entering the gearbox. Therefore, oil replacement is the only effective prevention of transmission, since otherwise you risk "kill" gearbox.
