[Public-List] shaft zinc

[Stephen gwyn via Public-List]

I had this problem last haulout. The threads on the bronze prop
zinc holder of the CMPN-B prop zinc had worn out after only 15
years. Replacing it turned out to be fairly easy with the right
tools: a length of 2x4 to wedged between the prop and the hull to
keep the prop from turning and a BIG wrench to turn the prop nut
holder. Luckily, I'm on good terms with the people in the yard
and they volunteered to lend me the 30-inch wrench. Out of the
water with someone else holding the 2x4, it took all of 5
minutes. In the water would be trickier.

I use locktite blue to keep the screw in.
