damp feet in an 18

[redsonfly]

Short of raising the floor in the 18, what fixes have worked the best on a 1989 model year boat (drain through transom)?
Has anyone tied the port cockpit drain to the starboard through hull drain the way others have done on the 23's? Is there enough room to do that?
motor is a 130 hp yamaha 2 stroke v4, batteries in the console, oil tank in port reach down area of transom (below the drop in bucket).
Things I am considering are to silicone seal off the rear molded in bait well and going to the TH marine ball scuppers... Any other suggestions?
