[C320-list] Hi all - question about water in the bilge

[Christian]

If salt water, and its coming from the section behind the bilge pump, I
would suspect any component of your raw water cooling system.  Is the water
more noticeable when engine running? Check if your raw water pump is
leaking, crack in hose on any component of your raw water system (thru hull
to pump, pump to heat exchanger, and the exhaust elbow to your aqua
muffler, and around the perimeter of your aqua muffler).  Are you seeing
any water in the pan beneath the engine?  Another thing to check is your
raw water vent loop anti siphon.  On a Perkins '94, the vent loop is
usually attached to the engine compartment fiberglass just port of the heat
exchange unit.  Your duck bill might have gone bad, and spraying water
while engine is running (this is an especially bad mounting place imho for
salt water sailing, as the this is near some electrical wiring, hastening
corrosion if spraying salt water).
