Keel cooling system
The M65 and M85T may be purchased in a form
suitable for keel cooling. The engine connections
provided for the cooler are to suit 32mm outside
diameter rigid pipe, as shown in (A) and (B). The
connection for the flow to the keel cooler is shown at
(B1) and the return at (A1). The design data for the
keel cooler is shown in the table below.

The pipework between the engine and the cooler
should be as short and direct as is possible, but
should be sufficiently flexible to allow the engine to
move on its anti-vibration mounts.
The pipe 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/anti freeze mixture containing 50%
antifreeze, to ensure that the inhibitors included in the
antifreeze are present at a sufficient level to minimise
corrosion.
Note:
The illustrations show the connections on the
M65, but are the same on the M85T.
