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.

Can I reuse the quart pump?
Yes—clean it after use and store it for future lower unit services.

Do I really need to replace the oil drain gasket?
Replacing it during service helps maintain a proper seal after reinstalling the drain plug.

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