INFORMATION

2.5.12 Cooling liquid

The engine is cooled by cooling liquid. The capacity of this
system of the Whisper 6-8 is 2 litres and of the Whisper 12
3,5 litres.
We recommend not using water but cooling liquid that is
marketed for the use in combustion engines. Cooling liquid
protects the engine against frost to minus 25° C. Also it
protects the engine block against corrosion. One can fill
the engine via the filling cap on the exhaust manifold. Fill
up till the level is just below the filling cap. When the
engine is on temperature the liquid will expand and the
redundant liquid will be pressed into the expansion tank.
This tank has to be filled up till the mark. When cooling
liquid is not available clean fresh water could be used with

an additive of anti freeze. When using water with anti
freeze the right mixture has to be calculated according to
the information of the supplier of the anti freeze. When the
cooling is based on keel cooling or radiator cooling the
capacity of these coolers and piping has to be taken into
account calculating the right mixture. The cooling liquid in
the engine is pressurised and has a boiling point above
100° C. The temperature switch in the thermostat housing
switches at 110° C. When keel cooling or radiator cooling
is applied the cooling system is not pressurised. There
should be a special cap on the manifold without valves
leaving the connection to the expansion tank open. Refer
to the manual on keel cooling and radiator cooling.
