Why This 20 Hour Service Kit Matters

• Full synthetic protection: Helps support strong lubrication at startup and reliable protection under load.
• Cleaner service results: Fresh gaskets help reduce the chance of seepage when reinstalled correctly.
• Lower unit coverage: New gear lube supports smooth shifting and helps protect internal components.
• Fuel filtration refresh: A new primary fuel filter element helps reduce debris before it reaches key fuel system components.

FAQ

Why are there 2 lower unit drain gaskets in the kit?
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 every 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 with your service supplies for future lower unit changes.

Will this help with rough running caused by fuel issues?
A fresh primary fuel filter can help reduce debris-related fuel restriction, but it will not correct issues caused by stale fuel or water contamination in the tank.
