Has anyone successfully built a small water
dam for allowing repairs
just below the waterline?
I have made a dam out of 1/2 of a bucket, but I cannot get anything to seal the water
out successfully. T-Rex waterproof tape lost
its stick, and butyl rubber bedding compound did the same. I'm in a tidal river, with lots of green algae (<1 foot visibility).
The butyl rubber and the T-Rex tape adhere wonderfully to the bucket, or to dry hull
, but the brackish water completely defeats the adhesives.
My objective is to mount a stern saver onto my transom, just below the water line.
