After reading a keel boat caution posted in the CatalinaOwners forum I checked my keel bolts. They were not tight! I just bought a 1998 Tall mast, Wing keel, seldom used and just put in salt water the first time in Sept by me. Beautiful condition boat with loose bolts! Please do not ignore this caution! Resp. Chief

Clarification entry:
Sorry about not being clear enough. I am of course referring to loose nuts as the bolts are tight in the keel. Tighten your nuts!

Congrats on the boat, I almost bought one like it long ago.
I have always thought of the nuts as "washers" because the threads of the bolt are holding the load... am I wrong? And of course the nuts should be torqued. If bolts are loose then I would want to do more than simply tighten the nuts.

Assuming the 250 wing is lead, the bolts in most lead keels are cast in, head-down, so they aren't held just by the threads and shouldn't come loose in the casting itself. However, some compression in the base of the fiberglass stub could allow the nuts to become loose early in the boat's life--they probably should be checked then and periodically later on. It might be useful to find out from Catalina how much torque should be applied (unless it's in the Owner's Manual).

The book for the boat has no torque specs in it that I could find. Another member on CatalinaOwners quoted Hunter specs and 1/2" bolts are listed at 45 ft lbs. "When to tighten keel bolts (if ever)" is the post in case any of you want to go over and check this all out.

I would think this would be a good place for a split ring lock washer, as long as it is flat then they are tight enough.

I would agree with you about split washer use, plus I would think some sealer would be appropriate. Stainless steel threads on the bolt and nut do not bite into each other well since they are so hard. I may put regular steel split rings on the bolts as a little rust might help! The washer is surrounded by stainless so it couldn't cause a problem I would not think. I am glad to see that many people are reading this as it is really important! Chief

Yes, Locktite does make a good sealer. Chief
