Beneteau 1993 First 35s5 Keel Separation

Beneteau First 35s5 Mentor-on-the-Lake
Hi - I have a small gap between the keel and hull (see pic though this is right after haul out before Lake Erie slime cleaned off). The keel bolts are in good shape - no rust. I replaced the nuts (some rust) and tightened them. I notice when boat is on the hard some streaks of water coming down the keel I assume are coming from bottom of the hull. Given Beneteau has the structure molding pan on the bottom it is hard to see exactly what is going on where the keel directly meets the hull. I can only see bolts coming out of the structural molding pan.

My question is whether I should just try to patch this (and with what?) recognizing that may not be the ultimate/best fix, or, is there a risk this will get worse and I need to have keel re-bedded. Given it is a 1993 I’m not excited about putting in a lot of investment but rather getting by with the minimum as long as it is not going to lead to bigger problems. BTW is this a common problem w/ Beneteau?

Thanks.

good representation of the lunar surface…

best to check toque of all keel bots to ensure they meet specs. Do so when the boat isn’t resting on the keel. Then scrape open the crack and fill void with sealant, again while not having the boat resting on the keel.

whether or not a more thorough fix is needed is a wild guess but will be obvious after some watchful waiting.

It's common Beneteau does the keel hull joint with 3m 5200 . Pick up a tube of fast cure 5200 (sets in 24hrs )the regular can take up to 7days. Clean gap and remove paint 1/4 inch either side of gap and apply a bead all around keel
