I have a 92' Mercruiser 3.0 with a Alpha One Gen 2 outdrive. I have the transom and gimbal housing off of the boat, had to redo the transom and rebuild the motor. When I was looking at the transom housing (from the inboard side) where the exhaust bolts on, I noticed a hole on each side of the lower exhaust cavity. Is this normal? The holes are round and it does not look like something is broken.

Thanks, I just wanted to make sure that water would not back up through the exhaust. I did not know if there were supose to be plugs in the holes or not.
