Prop is a 14.75 diameter Mirage Plus. My guess would be the Opti has more torque in the lower rpm range than the carburated Black Max is the reason it can power a 21 Pitch.

I run mostly in the ocean and have not run it at WOT so I don't know what top rpm is but will let you know when i do. Whatever it is, I doubt it would make me change props.
