Yamaha Outboard Oil Change Kits FAQs

Can I use automotive engine oil in my Yamaha 4-stroke outboard engine?

Boaters often question the need for specialised marine motor oil for their Yamaha outboard, but the simple fact is that motor oil for automobiles is not suitable for marine engines. Yamaha outboard motors are very different from car engines and thus require a specific type of oil that is developed for use in a marine environment. The two types of engine oil that are made for Yamaha outboards are Yamalube 4M for four-stroke engines and Yamalube 2M for two-stroke engines. To gain a better understanding of why automotive oil is not suitable for marine engines, let's explore some of the main reasons.

Outboard Engine Load - The force exerted on outboard motors is usually more than what cars experience, so it requires greater energy for them to function properly. Yamalube 4M and 2M oils contain additives specifically designed to counteract this increased drag.

Yamaha Outboard Engine Speed - As compared to car engines, Yamaha outboard motors operate at a higher revolutions per minute (RPM) rate. This rate can range from 4500-6000 RPM, instead of the 2500 RPM car engines reach when on the highway. This rapid rotation can be quite taxing on the oil, potentially reducing its lubricity by breaking down the molecules. To combat this issue, Yamalube 4M and 2M outboard engine oils contain special polymers that remain stable when exposed to shear force, ensuring the oil continues to provide superior lubrication.
Yamaha Outboard Operating Temperature - Yamaha outboard motors use natural, cold water to cool the engine. Saltwater, however, can become solidified if its temperature goes beyond 170° F, blocking the cooling system and causing the engine to overheat and potentially become damaged. This is why the engine operates at a much lower temperature than a car and why Yamalube marine oils are formulated with specific cleansing, dispersing, and viscosity-modifying agents to address the particular needs of marine engines.
Outboard Operating Environment - Your Yamaha outboard motor relies on air taken straight from the surface of the water to function, as it is often in close proximity to it. Yamalube outboard engine oils are designed to offer distinct protection compared to other oils, containing a special combination of marine-specific anti-wear additives, shear-stable polymers, corrosion inhibitors, detergents, dispersants, and viscosity index improvers. In summary, they are much better at protecting the engine, having more resilience and resistance to corrosion than automotive engine oils.

How is Yamalube marine engine oil different?

Yamaha has devoted a great deal of time and money to develop outboard engine oil specifically engineered for the marine environment. Our Yamalube oil change kits feature marine engine oil that is crafted to withstand the most difficult circumstances an outboard motor may be exposed to. From extended periods of high-power running, intense acceleration at launch, or hours of trolling, genuine Yamalube engine oils are up for the challenge.

Yamalube's marine engine oil is designed to provide an optimal level of lubrication and corrosion resistance for outboard motors operating in a marine setting. It is especially effective in preventing ring stick, the accumulation of carbon, and the formation of varnish. Additionally, Yamalube's four-stroke oil has the most effective anti-foaming formula on the market, and it has been approved by the National Marine Manufacturers Association.

Are all oil filters the same?

Yamaha oil filters are specially designed to safeguard Yamaha outboard motors. The highest quality components and manufacturing processes are utilized in the production of these filters. This involves the use of specific filter media and metal filter media bases (in lieu of cardboard) to create filters that are more resilient and have improved filtering properties. Yamaha oil filters have the advantage of being made with superior materials and craftsmanship, thus outperforming and providing better protection than other aftermarket marine engine oil filters.

How do you remove old oil from your Yamaha outboard engine?

The two main methods for getting rid of used engine oil are extraction and taking out the oil pan's drain screw plug. A vacuum extractor is inserted through the dipstick tube and generates suction to pull out the oil. This procedure is quite clean and is one of the most popular among marine technicians. To access the drain screw, the plastic covers on larger V6 engines have to be detached. Make sure to have a large enough pan to catch the oil, as some engines can hold up to seven quarts. Although not required, a petroleum sorbent pad is recommended to catch any drops and keep the driveway or yard neat.

In areas where the temperature is low, it is a good idea to turn the engine on before draining the oil to make it thinner. It is advisable to do the oil change as the initial step of the service, as this will allow you to take out the largest amount of dirty oil from the pan and reduce the risk of the new oil becoming contaminated.

How do you install a new oil filter and add fresh oil to your Yamaha outboard?

After you have examined your used oil and filter, put them aside to be thrown away in the right way. If you took out the drainage screw to drain the oil, put in a fresh crush gasket and attach the drain plug back again. Take out the new oil filter from its box and apply a light layer of new engine oil to the o-ring. Fasten the new oil filter in place and carefully tighten it up with the filter wrench to make sure the o-ring is in place without applying too much force.

Unscrew the yellow oil fill plug located at the top of the motor and pour in the new oil. It is advised to add just below the amount stated and measure the oil level with the dipstick after some time has passed so that the oil can properly be drained into the oil pan with the engine turned off. Filling up the oil to the lower end of the dipstick will assist you in noticing any changes to the oil level after the engine has been used. Now that the Yamaha 4-stroke oil change is done, you can move on to the other tasks included in the 100-hour service.
