Keep your Yamaha F350 V8 running strong with a 20 hour maintenance kit built around Yamalube 10W-30 Full Synthetic FC-W. This kit brings together the oil, filtration, and gearcase service items you need in one order—so you can knock out the first service interval with less guesswork. You get the right mix of engine oil for a full change, HD gear lube for the lower unit, fresh sealing gaskets, and both fuel-side filters to help protect performance and reliability.

FAQ

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

Do I need the 10-micron fuel/water separating filter if I already have the primary fuel filter?
They work together—the separator helps remove water and fine debris before fuel reaches the engine-mounted filter.

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

Should I replace the oil drain gasket every time?
Yes, replacing the drain gasket during service helps maintain a proper seal after reinstalling the plug.
