I know... I only post when I have a problem. This happened two weeks
ago. The bolt on the front outer piling holding the boat lift cradle
pulley sheared right off and the boat went in the drink. Photos of the
boat, the bolts, and some telltale corrosion streaks are stored at the
links below.

OK. So my question is.......... is there any way to diagnose a
galvanized bolts integrity before it rusts through like this again? I
can't seem to find my portable X-ray machine. I also can't quite
figure out how to do a simple swapout on the other three. I don't know
anybody who swaps their lift bolts out every few years!

Since apparently no one was injured, the important questions:

Was the boat damaged? Will your insurance cover any damages to the boat
or the lift?


Maybe you need to check the area for stray electrical currents...and
also change all the bolts and use nuts and bolts you can swap out every
season.
