Why This 20 Hour Service Kit Matters

• Correct oil for reliable protection: Fresh FC-W engine oil helps support smooth operation and reduces wear.
• Seals you can trust: New gaskets help reduce the chance of seepage when drain points are reinstalled.

• Fuel system support: A fresh primary fuel filter element helps reduce debris before it reaches sensitive components.

FAQ

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

Do I need to replace the oil drain gasket each time?
It is recommended during service to help maintain a proper seal after reinstalling the drain plug.

Is the quart pump reusable?
Yes—clean it after use and keep it for future lower unit services.

Will this kit work for my exact F115?
Confirm your engine’s required filter and primary fuel filter element before purchase to ensure you match the parts listed in this kit.
