Seawater 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 yacht in the follow-
ing raw water intake/discharge systems: Engine, (optional) generator, (optional)
air conditioning system and marine head (toilet) system.

Seawater Strainers

Seawater strainers are used in water pickup systems to filter incoming seawater. The typical layout is one strainer for
each of the following: Engine, (optional) generator and (optional) air conditioning system.
Seawater strainers are located near seawater intake valves (seacocks) and should be checked every time you use your
yacht for leaks and/or debris. If debris is found, clean the seawater 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 intake 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. Reassemble the seawater strainer.
6. Open the seacock before turning on the component or system.
• FLOODING HAZARD! The intake seacock that sends seawater to the strainer must be
closed before disassembling the seawater strainer to prevent the yacht from taking on water
through the seawater strainer assembly. Keep the intake seacock closed until the seawater
strainer is completely reassembled.
• SYSTEM DAMAGE HAZARD! After reassembling the seawater strainer, verify that the
intake seacock is open before component/system operation.

Raw Water Washdown (Option)

• The raw water washdown is located in the port rope locker on the
foredeck (see photograph to the right).
• The raw water washdown pump and the raw water intake seacock are
located in the utility room. Both can be accessed by removing the
galley steps.
• Make sure the seacock is OPEN before turning the raw water wash-
down system on. Activate the switch on the helm dash to direct raw
water to the washdown outlet.
