I have a 2013 Etec 30 hp equipped with a 4 blade high thrust prop that I use on my pleasure barge. The motor is in a well that is only ventilated by virtue of being open at the top. Consequently I get a lot of exhaust in that area, even at higher rpms. I tried sticking on a flexible hose over the exhaust relief port to direct that exhaust out over the side, which works well. However there is still exhaust coming out of the muffler drain hole lower down. If I block that hole what bad things could happen? Thanks!
