The only thing on your boat that might be considered a gray water holding
tank is the shower sump. If that is what you are talking about there
should
be a pump inside the sump. Sometimes they are automatic and sometimes you
need to flip a switch. There is a Sea Ray dealer in Quincy. Why don't you
give him a call?

The pump in the shower sump is automatically activated by a float switch
inside the sump. There will always be some water in the sump, as the pump
can't remove all of it. However, it is possible that the pump or float
switch has gone non-functional. The test is to simply run water down the
shower drain, and see if the sump pump cycles on and off. Given that Mike
has admitted that the fresh water pump is cycling, I think he's got a leak
in the fresh water delivery system. Almost certainly at one of the Whale
connectors.
