I have a 1997 h40.5 and I suspect that this factory practice will be found in all of the other 40.5's as well as many if not all of the other Hunter big boats.
The double galley sinks are joined with a connector and then a single corrugated hose runs to the seacock that is located under the small access cover directly under the sinks. This corrugated hose is not intended for below-waterline use. I am pretty sure of this. This factory practice was not picked up at my 10 year survey so it was not on my radar.
This past weekend, after I closed this seacock preparing to leave the boat, I noticed a small squirting stream of water coming from the hose at the seacock. As I touched the hose, it came off the seacock in my hand. It turned out that the water stream was from the standing water in the hose that rises to the sinks. The seacock was not leaking at all. This corrugated hose connects to a right-angle adapter by screwing onto the hose and then the adapter was pushed onto a short nipple that was threaded into the seacock. It was hard to see, but I think the nipple was just that- a plain threaded nipple as opposed to a hose barb. It was double clamped, but this setup is wrong for a number of reasons. Wrong kind of hose/adapter and no hose barb that would grip the hose after clamping.
Since this seacock, as well as all of my seacocks, is left open when we are using the boat, this presents a sinking hazard. I think the two head sinks have the same setup. I will be changing all of them before the boat goes back into the water next spring.
I must admit that I am surprised that Hunter would use this hose for this application. Every other hose on the other seacocks is a reinforced below-waterline rated hose with hose barbs used.
So check your hoses and if you have this same setup, please close your seacocks when not in use and don't leave your boat unattended with them open. And change out these hoses.
Sorry I don't have any pictures, but I will take some when I return to finish my winterization and I will update this thread.
