FAQ

Is this a complete “basic service” bundle?
Yes—this kit is built around the common 20 hour service items, including engine oil, oil filter, drain gasket, gear lube, lower unit gaskets, a fill pump, and a primary fuel filter element.

Why are there two lower unit drain gaskets included?
Lower unit service commonly uses gaskets at both the drain and vent screws, so this kit includes two to help replace both during the same service.

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You will receive the listed Yamaha oil filter part number, which also covers the superseded or alternate filter number shown in the kit contents.

Is gear lube pump fitment universal?
The included pump is a multi-purpose style designed for many common marine gear lube bottles and standard lower unit fill methods.
