Props
 
Can someone send me in the right direction on setting up the best props for my Sutphen.
many thanks!

The first thing you need to do is give some info about the boat, power, drives, gear ratio, etc. and if you have any speed data with any props.

I purchased the boat from a member here. "Jammin " I think it has history with other members of this forum. It's a 30' sutphen ocean pacer. It currently has twin 500hp's with konrad 540 drive's. Probs are P 5's, 14 " with 24.5 pitch. I will have to look into gear ratio. I'm slowly getting to know all the little details about the boat. Maybe Jammin will chime in on past performance etc.

Adding a little info to my previous question. The gear ratio in drives are 1:51:1. Boat wot rpm is 5100. Thanks

You are dialed in about as good as it gets with those props.
You're at 6% prop slip which is already very low for a straight bottom V and your rpms are where they should be.

Any recommendations on another prop to pick up some rpm and speed? I feel it has a little more.

I picked up about 300 rmp going from stock to labed props. That might get you what your looking for.

Chinewalk 01-09-2018 07:25 PM

My p5's are labed. I'm wondering if I need to go to a stock bravo1 25 pitch for more top end speed and max rpm
