New Prop Help Please..
Just finished up getting the motors freshened up. Now I want to see about getting some new props to get some more top end out of her without having to turn the motor 6000rpms. As of now @5000rpms the boat on GPS will 65-68mph.. I would like to do 75mph top@5500rpms. I have 3 blade props now? Any help will be appreciated. The boat is a 35ft Fountain Lightning with twin 468ci. BBChevy Engines. Appx. 1100hp combined.

The particular model of propeller you currently have and the gear ratio you have will help us to make the best suggestion.
I think you may end up with 4 blade propellers.
Call or email us and we can get you some test propellers.

The #'s on the props are
Quicksilver 48 13704 A40 23P. These are 3 Blade Props
Not sure on the gear ratio. The outdrives are Bravo ones however.
Hope this helps. Thanks for your help,
Chris

Yoyr slip % looks to be low with these propellers. I'd Lab Finish these to gain 300 rpm and take the speed that comes with that.
