most applications. Kohler Co. recommends using
closed heat exchanger cooling if the craft is operated in
saltwater or water with high silt content.
Provide service accessibility for the water-cooled
exhaust manifold pressure cap. Mount the coolant
recovery tank either to engine or craft stringer. Mount
the coolant recovery tank so that its surface level is the
same height or 2 in. (5 cm) max. below the level of the
pressure cap. See Figure 6-12 for a typicalinstallation.
See Figure 6-11 for coolant recovery tank connections.
Use supplied hose to connect to coolant recovery tank.
NOTE
If not using a coolant recovery tank, be sure that the
overflow hose is not immersed in the bilge water to
