I just replaced my 1989 4.3L mercruiser engine (has alpha 1 sterndrive) and launched the boat. I noticed it was taking on water about 1 gal/hr. Also noticed a strange gurgling noise at idle speed coming from behind the engine which comes and goes. Engine runs fine? I pulled the boat and filled the bilge with fresh water and noticed water coming out of exhaust port on the transom housing. The exhaust pipe was never removed and never had a previous problem with. Engine is fresh water cooled and exhaust manifolds / heat exchanger running at constant 160 degrees F. Is this a cracked or gasket leak in exhaust pipe?
