Water under cabin sole '89 3100 Convertible

[Uhehner]

Check for a limber hole in the engine room bulkhead.  Also check the anchor locker drain hole. My cabin would flood if the drain hole was plugged with debris and then the locker would fill and spill over the top. I never had to drill an inspection hole, the water would drain when the bow rose while running. If I had to guess where to drill an inspection hole it would be under the cabin steps as far aft as possible. Maybe drill a 1/4" test hole for starters.   Capt. George
