Seawater Systems
Seacocks
A seacock is a valve, controlled by a 90º lever, used to manage
the intake of seawater through the hull and below the water
line. Seacocks are typically used on your boat in the following
seawater intake systems:
•
Generator
•
Marine head (toilet)
•
Air conditioning system
Before using any of these systems, make sure that the system’s
seacock is Open and remains Open until the system is shut Off.
Seawater Strainers
•
Seawater strainers are used in water pickup systems to filter incoming seawater.
•
A seawater strainer is located near each system’s seacock.
•
Check the strainers for leaks and/or debris every time you use your boat.
•
If debris is found, clean the seawater strainer as follows:
1. Make sure the component/system (air conditioning system, etc . ) that the strainer is connected to is turned Off.
2. Close the seacock that sends seawater to the strainer you are about to clean. The seacock must remain closed
until the strainer is completely reassembled.
3. Take apart the seawater strainer.
4. Remove debris.
5. Flush strainer with water.
6. Reassemble the seawater strainer.
7. Open the seacock and check for leaks around the strainer. If no leaks are found, you may use the component
or system.

FLOODING HAZARD!
•
The seacock that sends seawater to the strainer must be CLOSED before disassembling the
seawater strainer to prevent the boat from taking on water through the seawater strainer
assembly. Keep the seacock CLOSED until the seawater strainer is completely reassembled.
SYSTEM DAMAGE HAZARD!
•
After reassembling the seawater strainer, make sure that the seacock valve is OPEN before
energizing the component/system.
