Max. capacity of the freshwater system in
keel cooled engines
This table shows engine volume excluding heat exchanger and the max. permitted total cooling system volume
with standard expansion tank, including keel cooler and other circuits such as an engine heater circuit or a cabin
heater circuit.
NOTE! If these values are exceeded, larger expansion tank must be installed.
