Yamaha | 20 Hour Service Kit | 20W-40 | F115

Keep your Yamaha F115 running clean, smooth, and protected with a complete 20 hour service maintenance kit built around Yamalube 20W-40 FC-W outboard engine oil. Designed for Yamaha F115 models produced 2006 and later, this bundle includes the core components commonly replaced at the initial break-in service interval so you can service your engine with confidence.

The 20 hour service is critical for replacing break-in oil, refreshing filtration, and servicing the lower unit. This kit combines engine oil, oil filtration, fuel filtration, gear case lube, new drain gaskets, and a fill pump into one convenient package.

FAQ

Is this the correct first service kit for a 2006+ F115?
Yes. This kit includes the core components commonly replaced during the 20 hour break-in service interval.

Why are two lower unit drain gaskets included?
Most lower units use sealing washers at both the drain and vent screws, so both should be replaced during service.

Does the oil filter part number matter?
You will receive the listed Yamaha filter part number, which also covers the referenced superseded number shown in the kit contents.
