Prop Selection for 2004 ProStar 197

My 2004 MC ProStar 197 w/power slot boat has a 13.7 X 15.5 with a C on the prop. I bought it from a ski school and they say the prop is cupped to give me extra pulling power out of the hole. I want the smallest possible and the boats in the slalom tournament last weekend on OLN made the wake look really small. A 4 Blade O.J. 13.7 X 19.5 was used according to MC, but they say this may not be the best combination for me as I live in Denver - high altitude impact. Has anyone achieved the smallest wake possible in high-altitude on a 2004 197 yet?

I'd call Eric Johnson at OJ Props and discuss w. him. I've typically seen the high altitude boats prop it way down to deal with the thin air. Going to a 19.5" would be in the wrong direction for the mile high city...the boat would suffer at holeshot and possibly speed holding ability.

Thanks for the suggestion - that is a great idea. Would you have contact information for Eric Johnson off hand?

As long as you're shopping, you should talk to Bill at www.acmemarine.com. Lots of people, myself included, have had good results with acme props.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

Prop Question Answered

Thanks guys. The 13.7 * 17 provides a smaller wake, especially at 22 and more off. The 15.5 provides for stronger pulling power, and a little noiser experience in the boat but no biggee. I suspect the 19.5 wold give even a softer wake - but I need the pulling power here in the high-altitude.
