FAQ

Is this kit correct for all 1995–1999 F50 models?
Yes. This configuration applies to 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.

Does this include enough oil?
Yes. Three quarts of Yamalube 20W-40 meet the typical oil capacity for routine F50 service.
