Prop and drive cable loss.

[Mike Caruso]

Rule 1, dont hit rocks, that is guaranteed to break your boat! Rule 2, set up a cable that won't lose prop if cable breaks. I make an adapter to take cable and stub shaft and solder together. The adapter is in front of strut and will not allow the prop to be lost if cable breaks. Yes it means to remove the flex cable the strut has to come off but it gives some security. Good engineering is hard to beat though. But of course there is always the chance that things can still go horribly wrong!! Oh yeah locking collars are just one more thing to be out of balance too!

2nd.... and hose over cable K.I.S.S. has worked for me since 1972.

Thanks
I agree on KISS principle and also concerned on balance at such high rpm. So I think I'll try hose retainer and if I ever get to close to the shore again and find the test failed I'll move on to phase two:) solder retainer.
Thanks for all of the input.
Some day I will share the after crash most embarrassing moments details! LOL
