The stoce props that were three blade, round ear, 26" pitch were cavitating at start up

What year is your hull?
What drives and gear ratio?

Julie

The hull is a 1996
Bravo 1 out drive

I'm not sure of the ratio

You need to run a Bravo I propeller on that hull, unless you have really heavy engines.

Julie

last weekend a tried a 24 pitch, four blade Hydromnotive, it seamed to have a good hole shot. I could not tell what my top end was doing there were 4-5 footer out there during testing, so I spent most of my time airborne.

Try it again in better water, for testing. This will give you a feel for the stern lift of a semi-cleaver propeller.

Julie

will do ...
Thank you

I agree with Julie that the Bravo 1 propellers in stock form are a great starting point. They will give you great all around performance on your vintage hull.

The trubble was that the stock props cavitated during accelleration.

Which props are you refering too?
