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

Take the guesswork out of your first service interval with a Yamaha XF425 20 hour service kit built around Yamalube 20W-40 FC-W. This kit is designed to cover the core service points in one order: engine oil, oil filtration, gearcase lube, and fuel filtration. It also includes the small sealing components that can slow a service down—oil drain O-ring and circlip, plus lower unit drain plug O-rings—so you can complete the job with clean seals and fewer surprises. With HD gear lube and a multi-purpose quart pump, the lower unit refill stays cleaner and easier.

FAQ

Why are O-rings and a circlip included in this kit?
They are common sealing and retention parts used during service, and replacing them helps maintain a clean seal and proper fit after reassembly.

Why does this kit include 3 quarts of HD gear lube?
Larger gearcases typically require more fluid volume, and extra lube helps ensure you can fill to the correct level without coming up short.

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.
