Sheared Keel Bolt Repair


New Member
My aft keelbolts sheared off just at the level of the bilge floor. The plan is to chip away the resin around the bolt to a sufficient depth to accept a coupling nut:

Then a new threaded rod would be screwed on from the top, and the whole thing refilled with resin.

1. What is the size and thread-count of the existing bolts? My boat is a '95 TPI. I'm away from the boat, otherwise I would measure it myself.
2. Does anyone have a better idea for repairing the bolts?
