What prop?
 

All right guru's.

Have the 27' magnum, converted to single engine, ol race boat.

Running little 468" BBC in it with an XR.

Makes a little over 500HP

Runs 66-68 @ 4500rpms' with a 3 blade 25 pitch prop when it is hooked up the best. I can make it spin a olot faster, but then it is all rooster tail and prop slip. It was the only prop I had that I could put an XR hub into.

I want to spin the engine around 5600 at WOT.

I also need a little more stern lift. What prop do I use?

call Brett and try a rev 4 22p

Rev 4 in 21 would be a good prop to test with.

Let us know.
