40.5 Aft Berth Leak

Hello Everyone

We just had a rain storm and I did not have the transition between my dodger and bimini up and now I got water dripping into my aft berth! :)


I am adding to the list of things to fix (exciting!) Anyone else have this issue? I think what is happening is water is getting into the helm via the cup holder/storage bin. Anyone tackle this?

Ouch!! Same design on my Hunter 386. I took my cockpit floor and aft cabin ceiling panel apart and re-installed with sealant when I replaced my autopilot linear drive. Hopefully, a simple matter of removing the cockpit floor and aft cabin ceiling panel and sealing the screw holes.

Most likely from the screw holes holding the aft cover for the steering quadrant and/or the wiring chase running through it. The steering station is pretty well sealed; you you can check it by removing the interior access piece in the aft cabin. It looks like it has leaked there before. Good luck. Also, an FYI, I had another leak in the aft cabin and found it was from the cockpit shower. I capped off the feed lines until I later installed valves in line to isolate it. Good luck; chasing leaks is always a PITA.

I think I found the issue, again the previous owner! :facepalm:


"Fresh" silicone around base, unlikely source.


Fresh silicone around accessible bolts... Still unlikely source for that volume of water.


Old Silicon instead of epoxy around autopilot. Likely source.



More old Silicon instead of epoxy in vacant screw holes. If a man named Tony wants to sell you a boat, don't.
