prop size

[Bushwacker]

You were told wrong! If you want more rpm, you need LESS diameter or pitch, or raise motor 1 hole (cavitation plate can be about 1" above bottom of boat if you run a cupped prop). I tried 14.5 x 19 and 14.25 x 17 stainless props; the 17" pitch prop picked up 200-300 rpm. Currently running a 14 1/8 x 20 4 blade SS, but it's a little too much for heavy load. Am considering having Bobby Soles cut it down some. He's a good source of prop info and also sells used props.
