Re: Yanmar Hydrolock
Don't know the answer to that, Tom.. Nauticat, for instance, pipes the vent overboard amidships, creating a telltale 'pisser' just below the pilothouse doors, similar to an outboard's cooling telltale.. pluggage is pretty obvious if you're watching. (a marina neighbour Nauticat didn't notice the flow had stopped and had a hydrolock in a remote cove)
Boats with decompression levers will have an easier time recovering from this that those without - and also those with a drain plug on the waterlift. Without a decompression lever I suppose you'd have to pull the injectors to clear it, assuming you haven't done serious damage at that point.
