Frequently Asked Questions about Yamalube Oil

Why Are Genuine Yamalube Motor Oil Kits Important?

Using the correct oil and filter at the recommended intervals is crucial for maintaining your Yamaha outboard. To make it convenient for our customers, we offer Yamaha oil change kits tailored for the most common Yamaha outboards.

Can I Use Automotive Engine Oil in My Yamaha Outboard Engine?

Yamaha outboard motors differ significantly from automotive engines. Therefore, it’s essential to avoid using regular automotive engine oils. Instead, use Yamalube oil specifically formulated for the demanding marine environment. Choose Yamalube 4M engine oil for four-stroke outboards and Yamalube 2M engine oil for two-stroke outboards.

How Is Yamalube Marine Engine Oil Different?

Yamaha has invested extensive time and resources to ensure that only the finest Yamalube marine oil, tailored for the challenging marine environment, goes into your Yamaha outboard engine. This oil is engineered to withstand harsh marine conditions and rigorous Yamaha outboard operations, including extended full-throttle use, aggressive acceleration, and extended trolling. Yamalube oil offers superior lubrication and anti-rust protection, guarding against issues like ring stick, carbon buildup, and varnish. Unlike passenger car oils, Yamalube 4-Stroke engine oils feature the best anti-foaming formula and are certified by the National Marine Manufacturers Association.

How Do I Install a New Yamaha Oil Filter and Add Fresh Yamalube Marine Oil?

After inspecting your old oil and filter for proper disposal, install a new crush gasket and the drain plug if you removed it. Lubricate the o-ring of the new Yamaha oil filter with a thin coat of fresh engine oil, then spin on the fresh Yamaha oil filter and gently tighten it with a filter wrench. Loosen the yellow oil fill plug on the engine’s top, pour in fresh oil, and allow it to drain into the oil pan. Add slightly less than the stated capacity and check the oil level on the dipstick. Filling to the lower level on the dipstick helps monitor oil level changes over time, completing your Yamaha 4-stroke outboard marine motor oil change.

How Do I Remove the Old Yamaha Oil Filter from my Yamaha Outboard Motor?

First, drain the used oil from your Yamaha outboard motor. Then, remove the engine oil filter. Depending on your Yamaha outboard model, the marine oil filter may have a drain lip to minimize mess when unscrewing it. Place absorbent rags or a small cup below the filter before removal. Use a correctly sized filter wrench or socket, with Yamaha offering a socket for their 5GH sized filters. Some technicians puncture the filter to allow trapped oil to drain back into the block, but this prevents filter disassembly for further inspection if desired.

What type of grease should I apply to my outboard motor?

For optimal performance and longevity, marine grease is the ideal choice for maintaining Yamaha outboard motors. Yamalube is designed specifically for Yamaha outboard motors, and aligns perfectly with Yamaha’s stringent engine specifications, delivering outstanding performance in both freshwater and saltwater environments.

The primary purpose of employing grease in mechanical applications is lubrication. However, given that outboard motors are frequently exposed to water and operate at high RPMs, they require a specialized grease formulated to repel water while maintaining peak performance.

Marine grease fulfills several vital roles for outboard motors:

1. Facilitates lubrication between metal components, enduring harsh conditions such as high temperatures, high pressures, shock loads, or slower speeds under heavy loads.
2. Lubricates concealed or challenging-to-access systems for extended durations, reducing the need for frequent replenishment.
3. Assists in long-term storage by forming a moisture-resistant seal, safeguarding against corrosion.
4. Shields against corrosion caused by contaminants and foreign substances.
5. Thanks to its viscosity compared to oil, grease helps maintain the effectiveness of deteriorated seals and prolongs their lifespan without any risk of leakage.

Grease is often chosen for applications where implementing an oil-based system proves too expensive or impractical to circulate and maintain.
