Remove seawater thru hulls?

[Joker757]

I'm removing and repainting the bottom of my boat and was wondering if I should remove the seawater thru hull valves? They are 12 years old. I've never had any issues with them. Is there something I should do to maintain them or is there a set interval to just replace them?

They should be brass ball valves with a brass insert. The only difference would be a teflon glide inside. If they're not leaking and operating sommthly, leave them be.

I agree, sometimes rebedding them can cause more problems. Best left to the professionals.

What kind of boat are we talking about?

Hi Joker, The decision is totally up to you, these are important parts to your boat.

If she were mine....I would leave them alone unless I thought I had a problem, or may have one in the future.

Good Luck on your paint job! Stay safe.

My thru-hulls were possibly original, which would make them 34 years old. They were corroded so badly that when I put a little torque on one with a wrench it literally snapped in half. So I replaced all mine.
Also as others have said the valves have to work. They're critical so I like the idea of having new ones.

If they still work..then no reason to replace them.

Your talking bottom anti fouling paint right ? if so and your question is if you should remove the through hull fittings so you can paint under them ? .. No you wouldnt ..

I just dont get the connection between painting the bottom and replacing the valves....

YD.

was wondering if these should be removed for painting the bottom and if I removed them then given thier age should they be replaced. I'm going to follow the advise here and just tape them and leave them alone. They work fine however given the critical nature of these was just wondering was there rule of thumb to replacing them.

As Luhrs noted, his were 34 when he replaced them. I have one of the same vintage and they work fine. My boats stay in the water and I move the handles quite frequently to keep them in good working order.

Good Luck, Joker.
