engine thruhull valve question with pic

[feltonmichael]

Should I replace this? The valve works fine does not leak and turns easily. the rest of the boat has proper wc tapered seacocks. Should I leave as is? or replace. I assume it came this way. it's on a 1966 pearson countess.

Yes. Replace it

[model 10]

Yes, replace it

[SVNeko]

If it works, replace it at next haulout.

[Tellie]

I agree. Replace it at the next haul out. Gate valves are pretty much obsolete on boats anymore. If this were to fail, looking at the pictures it would be a tough at sea repair. Plus, as there seems to be no hefty backing plate, there seems to be an awful lot of available leverage at the hull penetration with this setup that I would want to eliminate.

Plan to replace, looks typical of early Pearsons, like others above next haul-out, it's been that way for decades, time to upgrade a bit, and an easier to clean strainer too.
You have my dream boat.

Those who are willing to, please help me here. Whar are we looking at, and what is the issue? Doesn't look like mine, but I'm sure there are principles involved. I've got a lot more time over water at this point than time over either mechanical parts or tools ...

I had someone go through all the through holes with me a couple of months ago. The other person was satisfied with the through holes but I just had to take his word for it. Don't like that part. The hoses were all good too, but the clamps on the hose from the engine through hole had been put on (only 18 months ago) with, apparently, automotive clamps instead of marine quality. They were so rusty they broke into pieces as my guy took them off.

Doesn't matter how fresh and uncracked the hose is if it falls off ....

Here is a great primer on thru hulls. Seacock & Thru-Hull Primer/Pre Information Photo Gallery by Compass Marine at pbase.com

Thanks to everyone who replied I figured that I needed to replace them but I always like others input.

Replace, but while you're at it move the strainer(?) that is attached to the valve.

Keep the valve assembly as short as possible to avoid leverage. Seacock is best. Mount a strainer on a bulkhead, connected to the seacock by flexible hose.

While you have your wallet open, you might want to consider a modern see through strainer as well.

Cheers,

These types of valves are used frequently on commercial ships and I wonder why everyone is saying replace it? Maybe the age?

If the valve is in working order and has lasted a long time without failing, what is the ungency of replacing it. The only thing wrong here is it doesn't appear to have a stainer and it could use some cleaning/painting.

Yes, if it were mine I would probably replace it eventually and maybe move the thru hull to a more accessable location, but I would wait until the next hallout to do it.

In the meantime, it would clean the value, grease it and paint the bare spots.

You say it moves easily, but is it screwing the gate in and out. Those valves tend to have brass shafts which disappear after a while in salt water.

[feltonmichael]

Yes the valve stops the flow of water I recently changed hoses and there was zero leakage.
