prop hub conversion

Recommended Posts

I have done a couple of them now, they seem to hold up pretty well to 200hp popti max's

But have never tried a big hp motor.

I am pressing out the old small propshaft hub out, then machine the back of the prop open, install a fat shaft stainless hub without wear pads. Machine rear hub lock spacer and press it all back together.

The prop has a safety collar so if the hub should fail you wont loose the prop, kinka like the stock system.

I will do a couple more if anyone wants to try it.

Have only tried over hub style props, no through hubs.

Will need a prop and fat shaft hub takes me about week to get it done.

If this generates enough interest I will broach a new fatshaft hub and put them into production, make it a do it yourself kit.
