Russ, First I'd see what you got. May not need replacing. My boat is a 26 so may not be the same. I've read of some having a sacrificial bolt, meant to wear out eventually. Mine had a ferrule to work as a pulley. We borrowed a hydrolift at the marina and lifted the boat two feet clear of the water, with the keel straight down. The ferrule was in two pieces and had cut my cable. The bolt was very easy to remove. We went to town and found a like sized diameter brass tubing and reused the old bolt. A blind sailor two slips down from me held up the new frerrule and two washers and I slipped the bolt through. Less than five minutes. But the keel was not in our way. Good luck Kelly
