Re: Thru hull possibly leaking... what to do
look like someone put in bigger drains then it came with. those drains are just above the waterline. you could loosen the big white retainer nut and put a bead of sealer around the thur hull threads and retighten the nut. if it works then you will be good for another 30 years. if not then you will need to remove and rebid from both sides. looks to me like they did not use sealer and are relying on the epoxy only. do not use silicon seal or 5200. I would use 3m 4200 sealer as it is removable at a latter date
Thanks for the reply. If I loosen the big white retainer nut, will water starting rushing in? The boat is still in the water. I've not worked with thru-hulls before, so I'm a bit ignorant of their anatomy.
