Is there a formula or a website that has a calculator to help you figure out the optimal prop for your application? I need something to help me get in the ballpark.
Thanks,
Don

Don, go to www. hillspropellers.com, they have a propeller/speed calculator that will give you ballpark figures.

I have the new 496HO with a 24" 4 blade prop. The motor will only rev to 4500 rpm. Does anyone know what the difference will be between a 23" 3 blade and a 22" 4 blade in performance? I am wondering if the 22 will be better for top speed than the 23. If anyone has experience in this, please reply.

Well to answer my own question, I demoed a 23" 3 blade last weekend and it sucked! The prop had so much slip it wouldnt push the boat past 48 mph on gps. After 3 minutes I returned to the dock to put my 24" 4 blade back on. Wow what a difference. I Hit 60.2 mph on gps at 4600 rpm. I guess im stuck with that prop until I get more horses to push that prop to 5000 rpm. Unless anyone has any suggestions.

I wasn't aware that anyone made a 23" 4 blade. That sounds great I will try to find one. Thanks for the info.

I'm going to be in Havasu Sunday. If you would like I'll bring a 23" offshore for you to try. I'll be there Sunday through Tuesday.

I won't be in Havasu until cinco de mayo weekend. If you go then, we could hook up and I would love to try your prop.

I own a hallett 240 with a 500 hp. the guys at hill props will help, I called them, told them what motor and boat I had. They told me about a prop, I tried it and it worked ok, sent it back to them, they re worked it, and I tried it again and its works great, Hope this helps, even if I am a little behind the post.

I called Bronson Hill and I think I will use them soon after I get the re-call work finished on my 496HO. With the correct push rods in the engine I am hoping to get more RPMs and top speed.
