FAQ

Is this kit correct for all 2000–2004 Yamaha F50 models?
Yes. This kit is configured for Yamaha F50 outboards produced during those years.

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

Yes. Three quarts of Yamalube 20W-40 cover the typical oil capacity required for F50 service.
