refill you tank and use either a pool dye (best) or food coloring... I
bet you find the bilge water to have changed color. Then you just need
to find the evaporated color stain and is should lead you to the leak.

I would refill it once more and try it without the dye first... that
will confirm if Peggy's theory is correct without staining your boat...

The tank was bone dry.


My money is still on the pump diaphragm. If you have a leak, the water
has to be somewhere. You wouldn't be the first person to think there was
more in the tank than you thought and ran it dry.

You said you woke up the sound of the fresh water...did you mean the
sound of water running somewhere? Or just the hammering of the water pump?

If your heat exchanger were leaking, you wouldn't have water in the
engine, you'd have coolant in your water.


It's raw water cooled so all we would detect is the salt.


Ok, SALT in your fresh water then.
