Repair Instructions

General

If possible a condition test should be carried out be-
fore every major service correction, so that the engi-
nes condition can be established and any contributory
fault causes discovered. A condition test requires the
engine to be run so this should be carried out before
removal of the engine or any components is begun.
See Condition test, engine on page 32.
Action before repairing in the boat
1 Cut off battery supply.
2 Clean the outside of the engine.
NOTE! Ensure that the cleaning residues are col-
lected for destruction and do not accidentally af-
fect the environment. See also warning text un-
der point 12.
3 Work requiring action to cooling system: Close
sea cock and drain coolant from the sea water
and freshwater systems respectively.
WARNING! Ensure that the sea water intake is
properly closed and that water cannot enter
