Keel cooling system
This engine may be purchased in a form suitable
for keel cooling, using two separate coolers, one for
the cylinder jacket circuit and one for the aftercooler
circuit. Figure 2 shows the connections provided for
the coolers. The requirements for each section are as
follows:
Cylinder Jacket Circuit
Heat rejection.
TBA
Design value for the water
temperature
at the exit from the keel
cooler.
TBA
Design value for the water
flow through the cooler.
*Pipework to suit 45mm
(1.75”) bore hose
connections. TBA
Aftercooler Circuit
(Includes gearbox oil
cooler)
Heat rejection
TBA
Design value for the water
temperature
at the exit from the cooler.
TBA
Design value for the water
flow through the cooler.
Pipework to suit 45mm
(1.75”) bore hose
connections. TBA
Note: Under extreme conditions the water flow in the
jacket circuit may increase to 40 gallons/min.
The pipework between the engine and coolers should
be as short and direct as is possible, but should be
sufficiently flexible to allow the engine to move on it’s
flexible mountings. The layout should discourage the
formation of air locks, and venting points should be
provided wherever an air lock is likely to occur.
The keel cooling system should normally be filled with
a water/antifreeze mixture containing 50% antifreeze.
This mixture is necessary even in warm climates, as
the anti freeze contains corrosion inhibitors which
protect the engine cooling system.
