Removing seized seacocks from fiberglass boat
Hi,
I have a Cheoy Lee clipper. The prior owner plugged two of the thru hulls that were used for the head. I want to remove these thru hulls and glass and fair the hulls. My boat is on the hard right now. They both are very old, and seized bronze seacocks manufactured 30 years ago, one used for water intake, the other for waste discharge. The sea cocks are completely corroded and seized. The outer flange is 1 3/4". I've tried heat, liquid wrench, wood/hammer, etc. Since I have to glass and fair the original holes, is there any downside to me taking a hole saw and drilling a hole 2" and remove the thru hull in about 2 minutes instead of the hours and frustration that I have invested in the project thus far? |

Removing seized seacocks from fiberglass boat
Brute force is called for- a hole saw or a small grinder. In either case,
attack the outer flange. wrote in message oups.com... Hi, I have a Cheoy Lee clipper. The prior owner plugged two of the thru hulls that were used for the head.

Some amount of beveling/fairing is going to be required to repair the hole anyway so the grinder would probably be my 1st choice. Ed wrote in message oups.com... Hi, I have a Cheoy Lee clipper.

Removing seized seacocks from fiberglass boat
I have removed frozen through-hull fittings by cutting the flange nut with a
4" grinder with a cutoff wheel. Make 2 or three vertical cuts to separate the nut. You may want to use your larger holesaw if you applied enough heat to the flange to affect the fiberglass. There is little difference to fill a 1+1/2" hole as compared to a 2" hole. John "Ed Edelenbos" wrote in message t... "Jim Conlin" wrote in message ...
