Re: High Thrust Prop for Tohatsu 9.9 on Nonsuch 22
I have the 7" pitch 3 blade on my Tohatsu 6HP 4 stroke. I change from the stock 9" pitch (I think) prop to slow down the trolling speed. It also increased my top speed by .5 MPH. I think the 5" pitch might put you into the rev limiter, if it has one.
