Re: Drainage question on 1802
simple...you don't!! i have a 2005 1802 and you cant get under there....so far this is the only major fault with these boats...and apparently when they built them the never cleaned out the extra fiberglass crumbs, so they occasionally clog the drain holes and then u get problems, as i learned from the passage ways in the bildge at the stern. my only suggestion would be to get a long rod/coat hanger and try to fish it through the drain holes by the bildge in the middle of the boat (from under the step in the cabin)..other wise i'm happy overall with the boat. good luck
