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

Make your next routine service simple with a Yamaha F115 20 hour service kit built around Yamalube 20W-40 FC-W. This bundle includes the essentials for a clean oil change and lower unit service—engine oil, the correct Yamaha oil filter, fresh gaskets, gear lube, and a multi-purpose quart pump for an easier fill. You also get a primary fuel filter element to help keep fuel flow steady and reduce contaminants before they reach critical components.

Why This 20 Hour Service Kit Matters

• Correct oil for routine protection: Fresh FC-W engine oil helps support smooth operation and wear protection.

• Fuel-side refresh: A new primary fuel filter element helps reduce debris before it reaches sensitive fuel 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 during the same 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 your next lower unit service.

What does FC-W mean?
FC-W is a marine oil standard designed for four-stroke outboards in wet, high-load environments.
