I am still new to this boating thing, only in my 9th month of boat ownership. My question is concerning a drain plug hole in my transom. Not the drain for the hull, but there is a drain plug hole right directly under the engine. When the boat is in the water, this area fills with water. It never overfills into the boat, but I was just wondering what would happen if I put a plug in this hole? I hope I explained this right, sorry for the stupidness.<br />Thanks
