I just bought a 26 corsa a few months ago and just built an engine to put in that im estimating to be around 500 to 525 hp it has a bravo 1 with a nose cone 1:50 gears the boat is not 26 ft its more like 23 and im not sure how much it weighs its the old johnny red race boat so the cabin area is empty its just bare fiberglass so what props should I be trying out to turn the engine 5800 rpm. I also believe that the x dimension might have been raised. The bottom of the transom assembly measures 9 1/4 in to the bottom of the v

A lot depends on what you want to do.
1. Speed
2. Acceleration
3. Cruise
I think I would start off with a 4 blade 28 Bravo and see what that does. Borrowing props is best till you fine exactly what you need before buying. Or you might end up with 2-3 props you cant use.

Im probably gonna want to have two props one for top end speed and one for when I have the boat packed out with chicks and beer

Try something in the mid to upper 20 pitch range from a friend to get a base line. From there we can offer test propellers through our test program to get you dialed in.

Let us know if we can help.

first thing you do is run the prop you have and see what you get for performance. if boat is significantly more powerful than before, be ready to pull back on the throttle. you don't wanna hit 7000 just to see what wot rpm is. of course, if it has a 21 mirage, you know you need more than that before you even put the drive back on. but generally getting a baseline with an already paid for prop is a better starting point than swag. although when it comes from brett it ain't really swag. lightspeed used to own this boat when it was TRS rigged.

I have a 25" Mirage plus and a 26" Hydromotive Q4 I don't need. PM me, I might be near by.
