5.4 Keel Cooling System: M135 and M130C Engine
Both engine models may be purchased in a form suitable for keel cooling, using a cooler for the engine circuit.
Figure 3 shows the connections provided for the cooler.

Note: Under extreme conditions the water ow in the system may increase to 180 l/min (40 gallons/min).
Pipework should have a clear bore of 38mm (1.5”)
The pipework between the engine and the cooler should be as short and direct as is possible but should be
sufciently exible to allow the engine to move on it’s exible 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 lled 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.
