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 yacht in the following
raw water intake/discharge systems: Engines, generator system, (optional) air
conditioning system and standard marine head (toilet) system.
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, optional
generator 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 yacht for leaks and/or debris. If debris is found,
clean the raw strainer as follows:
1. Make sure the component/system (engine, optional
generator, etc.) 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 reas-
sembled.
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.
Raw Water Washdown (Option)
The raw water washdown pump is located near the shower sump pump holding tank. The raw water faucet is located
inside the port side tub on the foredeck (see drawing above).

CLOSED before disassembling the raw water strainer to prevent the yacht 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.
