Does that hydrofoil help with cavatation having a over hub prop like this ? I have been looking for opinions on line but this is first one i have seen same as mine

[@glennosgarage]

It was mostly just stability that I was after. I can't say I really had any cavitation issues before.

on the end of main shaft that heads up to motor, there is groove for o ring, did you put that on or is it not supposed to have one"? the reason I asked is we feel we seem a o ring in kit that is where i put mine but was certain there was not one when i took mine apart?

I forgot to put that o'ring on. Yes I do think it's meant to be there. I'm not sure on its purpose. Possibly to stop water getting in and causing corrosion. But that's just a guess.

Why would you use the same bushing you damaged by threading it to remove? It no longer functions as a bushing now, only as a seal holder and not for long as the seal will fail from the wear introduced from the damaged bushing.

[@glennosgarage]

Yes your right. Ideally replacing the bushing is the best thing to do. Many people do it this way with lasting results. I used what I had to get the job done. If you tap the bush using the smallest possible tap then you wont loose much of your internal diameter.
