Yamaha 4 Stroke Genuine Yamalube Outboard Motor Oil Change kits

Yamaha 4-Stroke Oil Change Kits Resources and Information

Changing the oil of your Yamaha outboard is a critical maintenance task that should be performed every 100 hours of engine operation or annually—whichever comes first. Depending on usage conditions, you may need to change your Yamaha motor’s oil a bit more frequently.

However, PartsVu’s Yamaha outboard oil change kits make the job easy. The kits include everything you need to perform an oil change, such as a Yamaha oil filter, drain plug gasket, and the appropriate Yamalube marine engine oil in the correct quantities. The Yamalube oil included in the kits comes in three different oil weights: 10W-30, 20W-40, and 5W-30 Synthetic.

Additionally, we offer a number of resources to help you with the task of changing your Yamaha outboard engine oil, including:

Yamaha Outboard Oil Change Kits FAQs

Can I use my car engine oil in my Yamaha outboard motor?

Many boaters inquire about substituting automotive engine oil for specialized marine motor oil in their Yamaha outboard engines. However, it's important to note that car engine oil isn't suitable for marine engines like Yamaha outboards. These outboard motors have distinct requirements, necessitating specific oil formulations tailored for marine environments. Yamaha offers two types of engine oils for their outboards: Yamalube 4M for four-stroke engines and Yamalube 2M for two-stroke engines. To understand why automotive oil isn't appropriate for marine engines, let's explore some key reasons.

Outboard Engine Load: Outboard motors endure greater forces than car engines, requiring oils with additives designed to counteract increased drag, as found in Yamalube 4M and 2M oils.

Yamaha Outboard Engine Speed: Yamaha outboard motors operate at higher RPM rates than car engines, which can strain oil lubrication. Yamalube oils contain stabilizing polymers to maintain lubrication under rapid rotation.

Yamaha Outboard Operating Temperature: Marine engines operate at lower temperatures than cars, which is especially crucial as saltwater can solidify, obstructing cooling systems. Yamalube oils incorporate specific additives to address marine engine cooling needs.

Outboard Operating Environment: Your Yamaha outboard motor operates using air directly from the water's surface due to its frequent proximity to it. Yamalube outboard engine oils are crafted to provide unique protection beyond that of standard oils, featuring an exclusive blend of marine-specific anti-wear additives, shear-stable polymers, corrosion inhibitors, detergents, dispersants, and viscosity index improvers. Essentially, they excel in safeguarding the engine, offering enhanced durability and superior corrosion resistance compared to traditional automotive engine oils.

How are Yamalube oils different than other marine engine oils?

Yamaha has invested significantly in developing outboard engine oil, which adds value to PartsVu's Yamaha oil change kits. These kits contain marine engine oil specially formulated to endure the harshest conditions an outboard motor might face, whether prolonged high-power operation, sudden accelerations, or extended trolling periods. Yamalube engine oils stand ready to meet these challenges head-on.

Crafted for optimal lubrication and corrosion protection, Yamalube's marine engine oil excels in preventing issues like ring stick, carbon buildup, and varnish formation in marine outboard motors. Moreover, its four-stroke oil features an industry-leading anti-foaming formula, earning the seal of approval from the National Marine Manufacturers Association.

Outboard engine filters—are they all the same?

Yamaha oil filters are meticulously engineered to protect Yamaha outboard motors, employing only the finest quality materials and state-of-the-art manufacturing techniques. These filters feature a unique construction that includes specific filter media and metal bases instead of cardboard, resulting in increased durability and enhanced filtering capabilities. Crafted with excellence in materials and workmanship, Yamaha oil filters deliver superior performance and protection compared to other aftermarket marine engine oil filters.

How do you properly perform a Yamaha outboard engine oil change?

To summarize the steps, there are primarily two techniques for disposing of used engine oil: extraction and draining via the oil pan's drain plug. The extraction method involves using a vacuum extractor, which is inserted through the dipstick tube to suction the oil out. This method is notably clean and favored by many marine technicians. For the draining method, particularly on larger V6 engines, you must remove the plastic covers to access the drain plug. It's essential to use a sufficiently large pan to catch the oil, as engine capacities can reach up to seven quarts. While not mandatory, employing a petroleum sorbent pad to absorb any spills is recommended to maintain cleanliness in your driveway or yard.

In colder climates, warming up the engine before draining the oil is beneficial, as it makes the oil flow more easily. Conducting the oil change at the beginning of a service session is advisable to remove the maximum amount of contaminated oil from the pan, minimizing the chance of new oil contamination.

How do you install a new Yamaha oil filter and complete the Yamaha outboard oil change?

Once you've inspected your used oil and filter, set it aside for proper disposal. If you removed the drain screw to let the oil out, replace it with a new crush gasket and reinstall the drain plug. Open the new oil filter's packaging, coat its o-ring with a thin layer of fresh engine oil, and then secure the new filter in its position. Use the filter wrench to gently tighten it, ensuring the o-ring is properly seated without over-tightening.

Locate the yellow oil fill cap on the engine's top and begin adding the new oil. It's recommended to pour slightly less than the specified amount and then use the dipstick to check the oil level after letting it settle in the turned-off engine. Aiming for the lower mark on the dipstick when filling will help you monitor any changes in the oil level once the engine has been in operation. With the completion of the Yamaha 4-stroke oil change, you're ready to proceed with the other maintenance activities in the 100-hour service.
