    75hp…….

    seriously though, 5petal vs 7 petal. Big porting difference. Different ecu’s. Both great engines.

    The 150 and 200 PM engines are just recreational motor with bling and maybe cleanup in the inside... 225 PM has the 7 pedal front and the pistons are different. 150-200 have the same piston as the fish'n motors with 2mm rings. 225 PM has it's own piston and rings assy. with the rings being 1.5mm rings and no over sized piston from Merc.
