I just bought a 1978 200hp Black Max V-6. It seems all of the lower unit exhaust is coming out of the access hole to the bolt that holds the torque tab (zinc) instead of out of the prop hub. This engine has a 5" shaft extension on it (25") and has been doing this since I got it. I had the shop replace the impellor a little after we bought the engine but it was doing this before and after the install. What would cause this? I have heard of drilling the exhaust tubes on this engine for more power but dont know if this would cause this or not. There are no extra exhaust holes in the outside of the leg though.
Since this hole comes out of the water on plane it makes the exhaust very loud.
Thanks
