48 ENGINE ACCESSORIES – COOLING SYSTEM
Expansion tank
A separate expansion tank for engine coolant can be installed in an
easily accessible position and thereby make checking and filling of the
system considerably easier. The tank is manufactured of a semi-trans-
parent material to enable the checking of the coolant level.
Material: Plastic
Installation: Max 1.2 metres above the highest point of the engine.
Includes: Tank, pressure cap, fittings for installation.

Hot water outlet
A hot water connection is made to the engine cooling system which
allows the hot coolant water to circulate through a water heater. The
hot coolant heats up the water contained in the water heater. This then
provides a domestic hot water supply.
Recommended hose for engine/water heater:
Hose, int. diameter 16 mm, part no. 952969
Recommended stainless steel hose clips: part no. 961665
Recommended hose for domestic supply:
Hose, int. diameter 12.7 mm, part no. 952968
Recommended stainless steel hose clips: part no. 961665
Cooling water intake
The cooling water intake is a through-hull fitting with strainer, installed
through the bottom of the hull. For motor boats the strainer should
be directed forward. Once under way, the seawater is forced up into
the system. However, for sailing boats, the strainer should be directed
towards the rear of the boat in order to prevent seawater being forced
into the system when under sail with the engine shut down. When a
motor boat is being towed, the shut-off valve must be closed.
Includes: Through-hull fitting with strainer, fittings for pipe connection,
shut-off valve, hose clips.
