5.3 Water Heater
The water heater is located in the engine compart-
ment. It has a 120-volt element that is thermo-
statically controlled at the heater and activated
by a circuit breaker located in the 120-volt panel.
The water heater is also equipped with a heat
exchanger that is plumbed to the water cooling
system on one of the engines. The heat exchanger
will heat the water in the hot water tank whenever
that engine is operating.
Plumbing the heat exchanger to an engine is
standard on Monterey boats. For highest effi -
ciency, the engine heat exchanger is of the single
wall type. The fresh water supply could become
contaminated with engine coolant if the heat ex-
changer in the water heater fails and the engine
is equipped with the optional fresh water cooling
system.
MOST ENGINE COOLANT IS TOXIC AND CAN CAUSE
SERIOUS INJURY OR DEATH IF IT CONTAMINATES
THE FRESH WATER SUPPLY AND SOMEONE
DRINKS THE WATER. NEVER DRINK THE WATER
FROM THE FRESH WATER SYSTEM FAUCETS WHEN
THE ENGINE HEAT EXCHANGER IS ACTIVATED IN
THE WATER HEATER.
A high pressure relief valve protects the system
from excessive pressure. Always make sure all
air is purged from the water heater and lines be-
fore activating the water heater breaker. Refer
to the water heater owner’s manual for additional
information.
DO NOT SUPPLY CURRENT TO AN EMPTY WATER
HEATER. DAMAGE TO THE HEATER WILL RESULT.
THE SYSTEM MUST BE FILLED AND PRIMED
BEFORE USING THE WATER HEATER.
5.4 Shore Water Connection
The shore water connection allows the direct con-
nection of the water system to a shore side water
supply. This provides the system with a constant
supply of fresh water and minimizes the pressure
pump operation. A female inlet fi tting is mounted
in the stern equipment locker near the AC inlet
plugs. A pressure reducer is installed in the sys-
tem along with two check valves. One check valve
keeps water from running out of the shore water
inlet fi tting when the pressure pump operates.
The second provides protection for the pressure
pump when the shore water is connected.
To use shore water, connect a hose from the shore
water faucet to the shore water fi tting located in
the transom storage compartment. Next, turn
on the shore water. The pressure pump will not
run and the water in the boat’s water tank will
not be used.
Note: The water tank will not be fi lled by
connecting to shore water.
DO NOT MODIFY OR CHANGE THE SHORE
WATER INLET CONNECTOR WITH ANOTHER
TYPE WITHOUT CONSULTING MONTEREY BOATS
CUSTOMER SERVICE OR YOUR DEALER. THE USE
OF THE WRONG TYPE OF INLET CONNECTOR CAN
DAMAGE THE FRESH WATER SYSTEM.
A SHORE WATER CONNECTION PROVIDES AN
UNLIMITED SUPPLY OF WATER THAT COULD SINK
THE BOAT. YOU SHOULD MONITOR THE SYSTEM
FOR LEAKS WHEN IT IS CONNECTED AND ALWAYS
TURN THE SHORE WATER SUPPLY VALVE OFF
WHEN LEAVING THE BOAT UNATTENDED.
