The pump runs continously.
1 - Pump switch Bad, or ?
2 - Leak in system? No excess water in the boat
3 - Low water in the tank. Gauge shows 1/2 full.

Is there any adjustment to the switch on the pump? Or just replace the whole thing?
 
Make sure first all your valves are off. My Bridge sink was slightly cracked on from some rough seas and it took me a while to figure it out.
A leak or valve slightly on would not show in the bilge. It would either drain overboard or go to the sump box and be pumped overboard.

Jeff,

Take a look at your FW pump. If it has a screw in the middle of the four screws that hold on the pressure switch end, you may be able to adjust that screw to change the pressure that cuts off the pump. Sorry I don't have a picture, but it's just been too cold to go to the boat - not that I'm complaining, seeing how many folks have had their marinas collapse under snow load!

Here's a picture of my pump...The middle screw is the pressure adjustment screw...as Earthmover said, be sure all your valves are off and all the air is bled out of your system...
