FYI, so on a cougar there are 2 drain plugs in the front area. The furthest forward has a hose on it, the one at the rear does not, at least on mine it did not. 3/4 inch inside diameter hose works here, I put an adapter to join the extra piece that I cut to the existing hose and shoved it down into the keel. Put a hose and shoved it into the keel on the rear drain as well. Hopefully, this will keep that water going towards the rear of the boat instead of a locker in a downpour.
