Re: Keel Locking Bolt Problem
Just a possibility of what is going on here and I hope that I am wrong. If your boat was left with the keel up for long periods of time in the water, it will wallow out the keel bolt hole. In doing so it prevents the locking hole from lining up. This is how some Mac owners check for the keel without dropping it with some other measurements from the outside to see if the keel is getting worn.
So not to be a doomsayer but this you should check. Put her on a trailer, block up the keel and lower it from the boat. When this hole gets badly out of round (and what you describe is kinda a tell tale), it risks breaking from the boat as it is worn near the edge. This is why leaving one in the water with the keel up CAN be an issue. And before anyone flames me, I keep mine this way as I have no choice, my marina is too shallow. But, I keep an eye close to this issue. Also, it is only kept this way in fresh water.
