I've got a 93 wellcraft eclipse 196 S with a 5.0L Mercruiser. The prop that's on the boat is a 21P aluminum 3-blade. Currently I'm running 4100 RPM WOT with 3-4 people in the boat including me, and it's slow out of the hole.

We primarily use the boat to ski/wakeboard/tube. I'm looking at high 5 or 4-blade stainless. What pitch should I drop down to? On the high five, would I need a 19 or 17?

I'm pretty sure I'd need to drop down to a 17 in the 4 blade due to the larger diameter.

Any help/advice anyone could give would be appreciated.

Thanks,
Jeff

Re: Help selecting prop

What is your WOT operating range and what type of stern do you have?

Best I can find is recommended WOT RPM is 4400-4800. My outdrive is a Mercruiser Alpha 1 Gen 2 1.47/1 Gear ratio.
