Hi all. I'm new to this forum, so hope you guys can help! My Ben 42CC has a saltwater leak which produces about 4 litres a day. I've traced it to being aft of the engine compartment, doesn't appear to be any stopcocks from anywhere near, leaving I think only the engine exhaust outlet or something to do with the rudder. Shouldn't be exhaust as its above waterline, and I can't see anything around the rudder fittings, which are all glasses in from the top anyway. Any ideas please?
