Hey gang I was doing some spring cleaning in swimbridge locker and noticed a small leak. It is where my raw water exhaust connects to the below water exhaust port. It appears to be a plastic tube... pipe that is set into the hull. Upon inspection, the tube is cracked where you hook up the hose. No thru hull here. So it drips when I cut on the engine. I cant get the hoseclamp to tighten down enough to stop leak. Not bad but enough to repair. So can I epoxe the crack.. or glass it. Who has delt with this. Its a hunter 336. Thanks Rick

SAME PROBLEM
This will not be of any help, but I have a friend with a Hunter 36, who has this same problem. Please post up how you deal with this, and if he gets his taken care of, I will post up the results.

Cooling water exhaust VENTED LOOP?
Rick, Could it be the Vented Loop that you are referring to? The cooling sea water goes to the vented loop before it goes to the cast iron mixing elbow to mix with the engine exhaust.The vented loop vent is, on my 1990 Hunter 33.5, a plastic device that is threaded into a stainless u-tube. This is actually a vacuum break devise. It closes when water flows thru it (to the mixing elbow) and lets air in when water pressure drops (engine off) to prevent syphoning water. With age and vibration (when engine is on) the plastic body can crack and leak. It then needs to be replaced. It's not a very expensive part, but you hve to find a source. I found mine at JT's Chanderly in Newport, RI. I can't remember the manufacturer, but they were in FL. Hunter should be able to point you to one. Mine cracked because of the way it was mounted to the bulkhead. It put side pressure on the body causing the rear of the threads to be in tension and the forward threads to be in compression. Use a stack of SS washers to stand the SS u-tube off the bulkhead to remove side pressure on the plastic body.
