self bailing decks

[msbhammer]

You can go with a larger drain as well. A drain with a ball in it is much safer as well. Seen alot of them on E-BAy.
But they are bigger in size. You will have to get a hose adapter that goes from 1 1/2 to 1" wich they do make and sell at west Marine. But be carefull, make sure you have enough clearance under the deck for them to fit. It might be tight.
