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

Keep your Yamaha F225, F250, and F300 4.2L V6 routine maintenance simple with a 20 hour service kit built around Yamalube 20W-40 FC-W. This kit bundles the oil volume you typically need for service, a matching Yamaha oil filter, and fresh gaskets to help seal drain points after the job is done. For the lower unit, you get HD gear lube with new drain gaskets plus a multi-purpose quart pump for a cleaner, easier refill. Fuel-side protection is also included with a primary fuel filter element and a Yamaha 10-micron fuel/water separating filter to help reduce water and debris before it reaches critical components.

FAQ

Why does this kit include a gallon plus 3 quarts of engine oil?
V6 outboards often require higher oil capacity, and the extra quarts help you top off to the correct fill 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 do?
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.
