Our's is a 1980 Striper 15. We've had two engines on it. A 1980 Evinrude 70 and and 1988. The 1988 is a bigger engine (more displacement) with more actual power - maybe this was when they changed to rating power at the prop.We've used three different props.
13x19 - SST (stainless)- original prop on 1980 motor
13x17 - aluminum - original prop on 1988 motor
13x15 - aluminum
With the old motor, the 13x19 was too big for skiing. The 13x15 was best, but would rev out early (you could not hit max throttle and stay less than 6000 rpm).
With the new motor, the 13x17 worked well. I think the 13x19 SST actually works best - it seems to get a better bite pulling me up on one ski.
All are OMC props. If I had to pick one new prop, I'd probably get a 13x17 stainless. The stainless really seems to bite the water better under heavy load.
