Gel coat is tough, I’d start with a wool pad and medium cut polish. I’ve been impressed with both the cutting and finishing capabilities of wool. 

So I found out allllllll about those connectors  today once I can figure out how to post images I can help everyone understand the last post lol!!!

basicly b is high thermal and balck

There is gray green and others...

p and s are male and female metal conector type.

dto6 is the connector housing type...

I will also put up the final final design.... but this should let me keep the oem warenty.  So I can plug it all back in if things need fixing.

 I ran the calcs and I got a different number.  The shaft is 1.125 I assumed a yield strength of 100,000 psi.  moment=yeild(I)/r  moment = 14,000 in lbs. at 9" 1500 lbs will yield the shaft.  did I do it wrong?

I did use a 1.25" shaft for some reason.  Never do math in public!

Yeah.  I bought the lightest compound.  If that doesn't work then I will get more aggressive.  Boat has looked like glass most of the time I have owned it, all elbow grease and beer.   Last year or 2, I have not done as good a job on it, but it lives inside.
