[Public-list] Missing Thru-hull?

[Amy & David Swanson]

Hey -

My original speedlog transducer was 5/8" diameter where it went through the 
hull.  It was long dead when I bought the boat.  Since I thought I might 
replace it some day, rather than permanently close the hole, I put a 5/8" 
bronze bolt through the hole, with washers, nut, and bedding compound. 
Don't use stainless (which is cheaper & easier to find), it does bad things 
without air.  This has remained solid for a number of years.  Cost was less 
that $15 total, and less work than properly re-fiberglassing the hole.

One could also just fill it with epoxy putty, perhaps with some fiberglass 
cloth on both sides, and probably get away with it but I would be worried 
forever more if I did that.  Grinding out a bevel on each side & properly 
re-glassing it would be a lot better if you are sure you will never use the 
hole again.
