Re: Prop Size
Re: Prop Size
It is a 9" pitch.The 9" is probably what it came with.Not necessary to know the diameter;diameter will follow design for your motor.You really shouldn't make a prop change without a tach.
also a gps for speed is ideal.A tiny tach is about $40 very easy install and the one for your motor will work on any 2 cylinder 2 stroke.
If you tell us your boat info,typical load and a baseline test of max rpm and speed we can make a suggestion if more is possible.In the meantime read the stickies at the top of the page.
