When a 22.8 is level on a trailer,will rain water collect in the belly of the hull ,that does not flow the openend drain plug .Unless the boat is tilted and drained prior to launch, I think I'm holding many gallons of water that I cannot view by simply looking into the battery compartment.I'm a Mako newbee .And once in water, will acceleration force all residual water to the belge pump ? Thanks Gary
