A RUPTURED RAW WATER INTAKE OR PRESSURE LINE
COULD CAUSE THE BOAT TO TAKE ON WATER. ALWAYS
TURN THE RAW WATER SYSTEMS OFF AND CLOSE THE
THRU-VALVES WHEN LEAVING THE BOAT UNATTENDED.
8.4 Raw Water System Maintenance
The following items should be done routinely to
help maintain your raw water system:
• Check hoses, particularly the seawater supply
lines, for signs of deterioration. Tighten ttings
or replace deteriorated hoses and components
as necessary.
• Periodically remove and clean the water
strainer located near the intake side of the
washdown pump. To clean the strainer, make
sure the Raw Water switch is o and close
the valve at the thru-hull tting. Rotate the
strainer bowl counterclockwise to release it.
Remove and clean the screen with fresh water.
Lubricate the O-ring lightly with silicon or
Teon grease and reinstall the strainer bowl.
• Spray pumps and thru-hull valves with a pro-
tective oil periodically.
• Fishboxes and baitwells should be drained and
cleaned after each use.
• Operate all seacock valves at least once a
month to keep them operating properly.
SHOULD A HOSE RUPTURE, TURN THE PUMP OFF
IMMEDIATELY. ALWAYS CLOSE THE THRU-HULL VALVE
WHEN PERFORMING MAINTENANCE ON A SEAWATER PUMP.
THE BATTERIES MUST BE PROPERLY CHARGED.
OPERATING ANY PUMPS FROM A BATTERY WITH A LOW
CHARGE MAY LEAD TO A PUMP FAILURE.
THE RAW WATER SYSTEM MUST BE PROPERLY WINTERIZED
PRIOR TO WINTER LAY-UP. SEE SECTION ON WINTERIZING.
