Yamaha | 20 Hour Service Kit | LUB-20W40-FC-04

Stay ahead of routine maintenance on your Yamaha F350 V8 with a 20 hour service kit built around Yamalube 20W-40 FC-W. This kit bundles the core first-service items in one box—engine oil, a matching Yamaha oil filter, fresh gaskets, and fuel filtration components—so you are not piecing together parts at the last minute. For the lower unit, you get HD gear lube, new drain gaskets, and a quart pump to make the refill cleaner and easier.

Why This 20 Hour Service Kit Matters

• Correct oil volume: A gallon plus 3 quarts helps you reach the proper fill level for service.
• HD lower unit protection: Heavy-duty gear lube supports gear and bearing protection under higher loads.
• Sealing gaskets included: Helps reduce seepage at common drain points after service.
• Fuel filtration coverage: Primary filtration plus 10-micron water separation helps protect sensitive fuel components.
• Cleaner refills: The included pump makes bottom-up gearcase fills simpler and less messy.

FAQ

Why does this kit include a gallon plus 3 quarts of engine oil?
Higher-horsepower V8 outboards typically require more oil capacity, and the extra quarts help you top off to the correct level during service.

Why are there 2 lower unit drain gaskets included?
Most Yamaha gearcases use one gasket at the drain screw and one at the vent screw, so you can replace both during the same service.

What does the 10-micron fuel/water separating filter help with?
It helps capture fine debris while separating water from fuel before it reaches sensitive fuel system components.

Can I reuse the quart pump?
Yes—clean it after use and store it for your next lower unit service.
