Water coming in from running or just at rest? Pretty good leak for the pumps to come on only after an hour.

Mine was leaking at the rear rub rail. That area is impossible to glass from the inside like the rest of the boat is, so Fountain seals that joiunt with sealer, or at least they shoot some in there. Both my 27 and 32 leaked there. I cleaned out the sealer and filled with 5200. Now even my 32 never gets so much as a drop in the bilge. Quite a feat from the way it sits with the rub rail in the water.
Cooler drain into bilge?

Just had my 2007 35EX serviced for a leak. Ventilation hose under the port motor was not sealed correctly at the thru hull fitting.
It only leaked while resting as this part of the hull is out of the water while running.
