Compatible engine models
General compatibility includes Yamaha and Mariner 80/100 HP 2-stroke engines as well as 80XS/100 HP 4-stroke engines. Documented Yamaha applications include F75 from 2003-2005, F80 from 1999-2003, F90 from 2004-2005, and F100 from 1999-2003.

The impeller is also documented for the Selva Marlin E.F.I. 80 HP and 100 HP. No specific Mariner model codes or years are documented, so compatibility in that regard should be verified against the engine's original spare part number and the impeller's dimensions.
