Prop Preference for a 86 prostar

I'm tying to advantage of the lull between the Christmas holidays and Valentine's Day spending sprees and thought I would sneak in a new prop. I currently have a 13x13 3blade.... I would like to get a little more top end.... should I get to the 13x12? 3blade or 4blade? Brand?

BTW, I love this place!

If you're looking for more top end, neither reducing the pitch, nor going four blade is your answer. I don't know what your answer is, but Bill Weeks might. www.acmemarine.com

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.

I'll have to check my prostar on the prop size but I know my 84 -19 skier has a 13x13 LH.

A prostar with a 1:1 gear ratio and a factory prop will run a 13x13. If the prop is a CNC prop, i.e. acme, or OJ XMP, then the same target RPM/HP can be achieved with less pitch.

On skiertoskier.com website they claim a 2 mph gain with the 3 Blade XMP. I am planning on trying either an OJ or ACME CNC 3 blade prop this spring. I will post my results on which prop I select.

Scot,
I have an 86 as well.. I have always keeped with the OJ 13x13 LH that came with it. What is your top end now? If you are like me I'm spoiled having a smooth surface behind the boat... I mean there is zero wake. I wonder if you would loose a little of that by changing props. Keep us posted.

What rooster tail I had at 22 off seemed to flatten out a bit with my prop change. The before picture is a frame grab and poor quality, but will give you a little basis of comparison, albeit a different hull design. Pics to follow.

Doug, Is the second shot at 36 as well?
I'll get some wake (or lack there of) pics out as soon as I get her back in the water.
