Raw Water Systems
Seacocks
Seacocks are valves which are typically used to manage the intake
of raw water through the hull below the water line (raw water intake
seacocks). Seacocks may also be used to discharge waste or water
through the hull below the water line (discharge seacocks).
Seacocks are controlled by a 90º lever and are used on your boat in
the following raw water intake/discharge systems: air conditioning
system and some marine head (toilet) systems.
Raw Water Strainers
Raw water strainers are used in water pickup systems to filter incoming raw water. The typical layout is one strainer
for each of the following: Engine, and optional air conditioning system. Raw water strainers are located near raw
water intake valves (seacocks) and should be checked every time you use your boat for leaks and/or debris. If debris
is found, clean the raw strainer as follows:
1. Make sure the component/system (engine, air conditioning) that the strainer is connected to is turned OFF.
2. Close the seacock that sends raw water to the strainer you are about to clean. The seacock must remain closed
until the strainer is completely reassembled.
3. Take apart the raw water strainer.
4. Remove debris.
5. Flush strainer with water.
6. Reassemble the raw water strainer.
7. Open the seacock and check for leaks around the strainer. If no leaks are found, you may activate the component
or system.
Marine Head Systems
Your boat comes equipped with a marine head (toilet) and waste holding tank system. Be sure to read the manufac-
turer’s operation and maintenance manual (included in your boat’s owner’s packet).
•
Waste is routed directly from the head to the holding tank.
•
The holding tank is plumbed to a fitting on the aft deck for dockside pump-out and, if equipped, to a macerator
pump for pumping waste directly into the water through a discharge seacock (where regulations permit).
•
You can determine the content level of the holding tank by looking at the tank (located on the starboard side of the
bilge). We advise emptying the holding tank at every opportunity.

CAU TI ON!
SYSTEM DAMAGE HAZARD!
•
Before using a seawater intake system, verify that the system’s seacock is in the OPEN position before the
system is started and keep the seacock open until the system is shut off.
•
Close seacocks whenever systems will not be used for long periods of time.
!
CAUTI O N!
•
FLOODING HAZARD! The seacock that sends raw water to the strainer must be
CLOSED before disassembling the raw water strainer to prevent the boat from taking on
water through the raw water strainer assembly. Keep the seacock CLOSED until the raw
water strainer is completely reassembled.
•
SYSTEM DAMAGE HAZARD! After reassembling the raw water strainer, verify that the
seacock valve is OPEN before energizing the component/system.
