4 and 5 blade props?

[FishStretcher]

I have a Solas Amita4 on a Yamaha F100 13 x 15" pitch. I get great holeshot, 33MPH top end.Even when dragging a hydroshield under the boat, and a kicker.

Your boat is smaller and has a bit more power, and a bit lighter but quite similar. You might try that or the 17" pitch model. Depends on the gearcase ratio on your boat. I bet you could get 35-37 MPH with that setup with a regular anti-cavitation mounted fin.

The Solas Amita 4 props were ~$109 at boats.net for aluminum ones last year. Cheap enough to try, get close, and have as a spare if you want to get a stainless one later.

What prop would you all recommand for an 18SF with a 1998 Yamaha 115 four cylinder two stroke ? I don't know what size prop is on it presently & the boat is in storage but I do know that the blades were ground down when I bought the boat. Someone told me they were ground down because they were too big & would hit .
