HIGH WATER ALARM-BILGE
The high-water alarm warns the skipper of a possible
emergency in the bilge area. There is an automatic fl oat
switch installed in the center bilge. If the water rises over
a predetermined level the bilge switch sends a signal to the
helm mounted alarm. This sump fl oat switch normally is
elevated from the position of the automatic bilge pump
switches.
If the alarm sounds bring the vessel back to an idled posi-
tion in neutral and turn off the engines. Open the engine
hatch and fi nd the cause of the problem.
Possible causes are:
1. Engine or generator hose leak.
2. IPS gasket leak between hull and drive.
3. Muffl ers or exhaust hose leak.
4. Hull leak due to striking an object.
5. Water or waste tank leak.
