Seawater Systems
Seacocks
Thru-hull inlet or outlet fittings near or below the waterline fea-
ture seacock valves. You can close a seacock to stop water entry:
• If the hose connected to the seacock fails, or;
• To work on equipment served by the seacock.
Seacocks are used on your boat in seawater intake or liquid dis-
charge systems including, but not limited to:
• Air conditioner
• Marine head (toilet)
Before using any system with a seacock, make sure the seacock is Open and stays Open until the system is shut Off.
Seawater Strainers
• Seawater strainers are used to filter incoming seawater in some seawater-intake systems.
• If equipped, the seawater strainer is located near the seawater-intake system’s seacock.
• Check the strainers for leaks and/or debris every time you use your boat.
• Refer to the seawater strainer instruction sheet for cleaning and maintenance information.
FLOODING & SWAMPING HAZARD!
• Close the seacock(s) when leaving the boat unattended for any length of time.
• If a seacock is left open, a hose failure could flood the bilge, swamp the batteries and the
engines, and even sink the boat.
WARNING!
!
SYSTEM DAMAGE HAZARD!
• BEFORE using any system that has a seacock, make sure that the system’s seacock is Open.

even sink the boat.
• Keep the seacock Closed until the seawater strainer is completely reassembled.
SYSTEM DAMAGE HAZARD!
• After putting the seawater strainer back together, make sure that the seacock valve is Open
BEFORE using the component/system.
