Guys I need a new prop on my model 40D Tohatsu. It's on the back of a 1548 semi v aluminum duck boat. It won't be pushing heavy loads very much and I am basically shooting for speed.....racing to public duck holes. I am looking at the power tech SCH3 but I am new to props and outboards. I think I want to go with something in the 14p range, but I dont know about, rake, cup, or diameter.....thanks for any help you can give me on this

That is their semi cleaver SS and it ought to be a good fit, if your gear ratio is 1.85:1, please verify this. I am also assuming the boat you are talking about is made by G3, with that prop you should be able to do about 35 MPH.

It is an Eclipse boat (guy from excell, before they became excell) Ill check the gear ratio when I get out of class....but I ran 35 the other day with the old 12 pitch OEM prop from power tech....I hope it will go faster with the new one....
