Thru-hull leak

[bailsout]

Has anyone ever seen the thru-hull that houses the cutlass bearing leak around the thru-hull between it and the hull? Or seen such a piece that is flanged without any mounting hulls? First time for me. Recommended bedding adhesive for re- installing the thru-hull? The flanged part is only about one quarter inch.

Not too clear on what you describe. Is is a bolted flanged fitting type? I think you meant no bolts though. "hulls". Leaking between the hull and flange? Are you sure it's where it is leaking, or just stained?
Is the flange outside? or on the inside of the hull?

Are you describing the propeller shaft stern gland?
Post a pic of yours pls.

He's talking about the stern gland stern tube, not a through-hull. Not cutless bearing, but stuffing box.

Sounds like he has a loose and unsealed stern gland, which can be very dangerous. I would suggest he immediately lift the boat and get it looked after.

Sometimes my boats have had nuts on studs and sometimes bolts. So I said holes for mounting. Yes the leak enters around the outside of the hru-hull. So the need for a good bedding compound or adhesive. This had all been replaced two years ago, but the leak began 5 months later and remains very slight.

Deblen,
Thank you for this. I'm not sure if my stern tube is bronze or stainless. I will see if the previous owner knows
