Looks like it's not bolted to anything and is held in place by the through hull threads and bedding adhesive.

Compass Marine also has an excellent how-to on a way to install with a backing plate that doesn't require bolts through the hull.

Other than the bonding wire which is easy to attach, I wouldn't worry about it. It looks like a "Buck Algonquin" seacock which are bronze. If they used 5200 or 4200 it's not moving. Granted, as previously posted it could be better but it shouldn't be a deal killer. It does look like it was just installed though. The bonding wire looks like it has a little "green" on it and the seacock looks to clean to be in service for very long. Just my 2 cents.

While it may be called a seacock , what is pictured is nothing more than a ball valve.

The valve choice and the insane concept of gluing it in place when it does have the ability too be bolted in would make me want a very careful survey.

Is this the OEM installation or some past yards work?

If this level of workmanship is through out the boat , I would consider finding a better assembled vessel.

ONE lack of understanding is OK, a boatload might be too much hassle..

Many things can be redone , with time and money to get a safe boat , but if its an OEM install , there may be many more issues even a great surveyor can not find in time.

FF, this is some fairly recent yard work. I believe it was done about a year ago. A further question I have is, with the bonding wire not connected has the thru-hull corroded to the point of weakness that it is likely to fail?

Doubtful even in a marina with current in the water,.

Many folks do not believe in grounding everything to become a big anode ,

I have seen many boats with ZERO bonding , still not with pink bronze after 3 or 4 decades.

>this is some fairly recent yard work<

Would be nice for the folks to know what yard , to put on there NEVER! EVER list.

I doubt it very much. In fact many european sailboats do not ground their thru hulls at all by design. We owned one for almost 8 years and it was never an issue.
