They are 150's and yes the boat is self bailing, when I had the bracket and transom done I had the drains moved to drain out the transom and closed the thru floor drains.

did you raise the floor, could you take a pic of your set up, i have a 225 yami on float bracket and am thinking about doing it , but some have said it won't work without raising deck.

No the floor did not get raised, I am getting ready to have the floor replaced and will keep it at the same height
