Water Heater

Most water heaters are electrically heated and
are equipped with a high-pressure relief valve
and thermostat for safety.
If your boat is equipped with a water heater, it will
come standard with a heat exchanger that will
use engine heat to heat the water.
Guidelines when operating the water heater:
• Fill the freshwater system or connect to city
water and bleed air from all lines.
• Turn on the water heater circuit breaker.
NOTICE: DO NOT turn on the water heater
circuit breaker switch unless the freshwater
system is charged and the water heater is filled.
Damage to the heating element will result if it
heats up with no water in the system. Some
water heaters are equipped with a
high-temperature limit switch to protect the
heating elements if the heater is activated with
no water in the tank. If the system does not
operate for any reason, turn off the water heater
breaker and push the reset button on the
heater.

RAW WATER SYSTEM

Raw water is seawater (non-drinking water).
Some boats use raw water systems for engine
cooling or head.
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.
Guidelines when operating a raw water system:
• Open the desired seacock.
• Turn on appropriate pump switch as required.
