Sorry if this is considered a cross post but it is both a motor and a sailing question.
My MD11c Sea cooled engine has developed a problem that after sailing for a few hours in anything other than smooth waters, there is no water coming out of the exhaust when I start the engine, after much pratting around I have found that if I pull the pipe that feeds water into the pump no water is present, but if I lower the pipe water flows and continues when I connect it back to the water pump. This cures the problem. The Sea water travels from the Inlet/sea cock/strainer to the gearbox and out of the gearbox to the pump. Is it possible I'm getting some kind of airlock in the gearbox or attached pipes? I have checked everything after the pump and it all seems clear. I havent changed anything in this area so I'm a bit confused
Thanks
