RAW WATER SYSTEM
Raw water is seawater (non-drinking water). Some boats use raw water systems for
engine cooling, head, and utility and cockpit washdowns. Some raw water systems
may supply two components and have a flow control valve for directing water flow.
Raw water systems include:
• An individual thru-hull raw water intake.
• A seacock and strainer. The seacock protects your boat from sinking if a
downstream hose or fitting would fail. Always close any seacock not in
use.
• A pump to draw water into the system. Engines may have belt- or pulley-
driven pumps; heads may have manual push/pull or electric pumps, and
utility and cockpit washdowns may have electric pumps.
• An outlet valve, fitting or nozzle.
Guidelines when operating a raw water system:
• Open the desired seacock.
• Adjust flow control valve (if equipped).
• Turn on appropriate pump switch as required.
