On the 3200SCR, several things drain into the bilge, including some rain water channels. So if you're in a place where it rains, your bilge will never be dry. Even when the bilge pump runs, it can't get the last bit of water out because of the siphon-breaker bend in the outlet hose. I've always got an inch or two of water down there.
On the other hand, if the float switch is up and/or the bilge pump is significantly submerged and the pump is not running, it's busted and needs to be fixed ASAP.
