I think Merek's concern is well founded because water pressure from a marina hose can be as high as 60PSI, so might overwhelm the impeller and flood the engine if left unattended. There is zero pressure when the boat is in the water at the dock or sailing. Big difference. Simply shutoff the water after stopping the engine and avoid the risk.

I know mine is. That should keep any raw water from entering the diesel. The T fitting would be a non-issue. I routinely leave the water intake through hull open while sailing, and on long trips, and I’ve never had a problem with the diesel flooding.

If your water pump does not stop the water flow (and it does not have to), you can easily overflow the muffler and the mixing elbow and fill the cylinder(s) with water through the exhaust valves. It does not have to happen (especially, if you are quick with closing the water tap after you stop the engine), but it can happen. If you want to be really paranoid about it, another issue is that the tee is either plastic (PVC) or brass; neither is recommended for under water fittings (PVC – not strong enough; brass – corrosion). just a though Marek (in Ottawa) _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
