Re: Bedding Deck Hardware With Butyl Tape
I have a transom-hung rudder, with two gudgeons mounted on the transom. When I replaced them last year I bedded them with MaineSail's butyl tape, since they are both above the waterline. I cranked down on the screws as much as I could, but toward the end of the season they loosened up. These things have big bronze backing plates and lock nuts, so I know the screws did not loosen. The butyl apparently oozed out enough for the bedding to become a little thinner.
Is butyl the right application for this, or should I look for a curing sealant to bed the gudgeons? If the latter, what would you recommend?
FWIW, I am replacing the Phillips head bolts with hex head, so in the future I should be able tighten them up mid-season without having to remove the rudder.
