Custom/Hybrid DIY repitch

[102nd7]

Looked and came up empty. Was wondering if anyone could give me a run down on how to repitch a prop

The thing no one ever addresses is how far you can go. If you pitching down at some point the blades will hit the wear ring and if your pitching up at some point the prop to wear ring clearance will be to great and you will loose optimal pump pressure. I can't imagine you can go more then a few degrees with out having to machine clearances.

That's why you have to start out with a casting that has angles close to what you want.

I use the DAI re-pitch . .


that would be Dave At Impros

I know that and also just recommend anyone use Impros. Just curious if anyone knows how many degrees you can go before welding or machining is needed.

The guy that always did repitching for me (Art Gomez/Jetworks/BlackJack Performance) said 1.5 - 2 degrees absolute maximum in each direction.

I took one to about 3.5 myself and IT DID require careful shaving to fit back into the pump. 2* +/- has been just fine for all of them that I've done. After I bend one I always set it on a flat srface with blades marked on the edge every inch. Then use a precision ruler to measure every blade at every inch to make sure they are all true. You'd be surprised how different they can be without ever vibrating.
