Raw Water System
8.5 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 fittings
or replace deteriorated hoses and components
as necessary.
• Periodically remove and clean the water strainer
located in the primary intake fitting for the sea
chest.
• Periodically remove and clean the water strainer
located near the intake side of the washdown
pump. Spray pumps and thru-hull valves with
a protective oil periodically.
• Fishboxes and livewells should be drained and
cleaned after each use.
• Operate all valves at least once a month to keep
them operating properly.
Cleaning the washdown pump water strainer:
1. To clean the strainer, make sure the Raw Water
Pump switch is off and close the valves at the
sea chest supply hose thru-hull fittings.
2. Rotate the strainer bowl counterclockwise to
release it.
3. Remove and clean the screen with fresh water.
4. Lubricate the O-ring lightly with silicon or Teflon
grease and reinstall the screen and strainer bowl.
