ok I didn't know where to put this thread so I'll try here first. anyone have a yamaha prop they wanna sell to fit my 08 50 yamaha 2 stroke. the motor was on a big v hull. it's a Michigan I believe 11x15 pitch. I put it on my 16 foot flat John b center console. at 57-5800 rpms I'm gettin 39 mph. would like to see if I could get a little more performance and lower te rpms? any suggestions?
