Today finally had the chance to test a Bravo 1 24P. Hole shot was greatly improved both full throttle start and gradual RPM start. At 3500 RPM's speed was 40MPH. At WOT,max RPM's was 4900 and speed was 57 MPH. I had 3 people and full tanks of gas. I know the test would have been better with half tanks, but didn't want to go to the gas station more then once. Temp was 100 and water had some chop. Do these results seem to show that the prop is might bet choice? thanks for any help.

I think you are getting close. 100o temps are the biggest problem (and the heavy fuel load) you had during this test. You should be able to pick up 100/200 RPM in cooler weather with a lighter load, putting you right where you need to be.
If that propeller is stock, it can worked for more efficient operation on your boat.
BTW, the engine compartments on the Heat are notoriously air restrictive. If you can get some fresh air into the engine compartment, that will help. There are lengthy threads on that subject. Just use the search function to get some ideas.

I have hydromotive P5X 24 pitch if anyone is interested. Make an offer. Good Condition. No hub. Only used a few times back when I had 1.35 gears. Now I have 1.50 gears and the prop is to small for my application.
