I refurbishing a 1991 13" sport and recently purchased a 1997 Yamaha 40hp engine. I searched around and cant figure out what is the best prop size is. I will be using the boat for cruising and a little waterskiing / Tubing with the kids.
Any suggestions? Thanks Andrew

Andrew,

I have a similar setup as you. I'm running a Power Tech SS prop. I'm not sure what the size is as I was unable to read the numbers that are stamped on it. Later this afternoon I'll take the prop off and see if I can decipher any other writing that may be on it.

My Power Tech SS prop provides pretty good speed for us, I'm able to pull a water skier, pull a tube and basically anything else we can think of.

I just want to buy one prop and want some advise before I do. Andrew

Hey Andrew,

I have a 79 13 Sport with a 1998 40hp 2 stroke turning a Solas Aluminum 11X15 prop. It seems to do well for me. The whole shot is good and top end is also good. I'm hooking up a tach very soon. I will update as soon as I know those numbers. My prop would cost you around $80 bucks plus shipping. If you run in shallow water. I would stay away from SS props.

Gook Luck......Ron

Thanks Ron,
Ive been told 11x14 and 12x13.
I'm just not sure. I'm not finished the boat yet and was hoping to narrow it down before I have to buy one.
Thanks Andrew

No problem.... I would think the 11x14 would be good also. I would imagine the whole shot with the 11x14 would be better than the 11x15. You may turn a few more RPMs with the 11x14 on top end. Either the 11x14 or the 11x15 would be good choices. Like I said, I don't have a tack. So, I'm going by what I think the engine should be sounding like to me. Not sure about your area but in the Virginia beach area we have propeller shops. The guy will sell you a prop and if your not satisfied. You can take it back and try a different prop until you get the one you like for the boat.
