Freedom Runner needs Prop

Postby infantryguru » Wed Jul 06, 2016 8:09 pm

Need some input on a prop for my airboat since mine came apart this past week. I had been wanting a new prop, just not this way. I was running a 6 blade warp drive but 3 blades gone and the rest damaged pretty bad. I have a 2002 16ft Freedom Craft boat with boxes so it's pretty heavy, but it dose have poly on the bottom. It is a direct drive 1971 or 72 Cadillac car motor, I believe 472 horsepower and runs good at 2800 RPMs. I've never run any other prop than the warp drive and have had pretty good push and able to get out of most places I go. I am looking for something that will have good snap and low end push, not looking for high speed. Appreciate your input.

On my 472 I ran quit a few props - 72" 2 Blade Q, 72" 3bld H, 72" 2 bld stump puller and 4 different wood props.

A few I wanted to try 3 bld cypress, 72" signature,74" NGQ.

The thinner blades perform like a old 2 stoke, Runs in a narrow power band at the top of it's rpm range. The wider 2 blades give you better across the rpm range.

Best pushing prop I owned was a 72LXL38 FAP Wood Paddle prop, but I would rather not run a wood prop after destroying a few.

Your probably best served to run a Q blade on a 472, they are proven as a do it all adjustable blade.

If it is a strong engine you may be able to run a 74 inch prop.
