Thru hulls for novices

I inherited a 24' sailboat and we are in the process of refitting. Thanks to the forum we have now completed the re-wire and have moved onto plumbing.

I have some concerns about the condition of the thru hull fittings which visually look quite degraded. I am unsure if they are brass or bronze and how long they have been in the boat. The last thing I want to deal with is a failed fitting. After researching on the forums it appears that ball valves are much preferred over our older gate valves. Regardless, our valves are no longer operational because the wheel is about to fall off.

Is there any way to inspect and assess the integrity of a thru hull fitting and valve with the boat in the water or on the tide grid? Are we going to get a warning that the fitting is failing with leaking before catastrophic failure? If the thru hull fitting is intact would people recommend leaving the fitting in place and thread on a new valve? Is replacing a thru hull fitting something a novice could do on a tide grid or would be need to haul the boat ?

Our stern thru hull looks like this:

Re: Thru hulls for novices

Without more info about age and electrolysis hard to say for sure. Pretty easy to change out thru hull and valve if you are on grid .Takes minutes when things go right.Probably thru hull portion is good.scrape with knife or chisel and look for good seal to hull. Good backing plates are in place? Turf the gate valves and get bronze ball, nylon seals. Quality. Should have softwood tapered plugs on a string next to each valve just in case of catastrophic failure.

Re: Thru hulls for novices



That's one scary looking through hull!

The handle on the gate valve looks ready to fall off. I kind of doubt that the ribbed hose is reinforced. Also, a single automotive-type hose clamp on what appears to be a below the waterline fitting is not good. Is there room, (or need) for a backing plate, on a through hull that seems to go directly through the bilge and keel?

What kind of boat?

If it were my boat, I would think about moving the through hull to another location where I could install a proper backing plate, and filling the hole in the bilge. The links that mitempo posed outline the process.

That photo should be in a marine book with the caption "what not to do" or "how many things do you see wrong with this photo?"

I would not touch it unless hauled. Not even to replace the hose.
