CHECKS AND SERVICE
Checking and changing of the impeller
The impeller can be damaged by e.g. lack of
water. Remove the cover on the sea water
pump. Draw out the shaft enough so that the
impeller's locking screw can be screwed out.
Holding the shaft, draw off the impeller. If the
impeller is damaged it must be changed.
Lock the impeller on the shaft with the
locking screw.
The flange is defective if the impeller and the
shaft can be rotated. A new flange can be
fitted after the pump has been removed.
Refit the cover with its gasket.
ELECTRICAL SYSTEM
Alternator
The engine is equipped with an
alternator. To ensure that the alternator,
with the builton regulator, functions
without interruptions, the following
important points must be observed:
1.
The main switch must never be
switched off until the engine has
stopped.
Otherwise would ruin the charging
regulator
2.
The battery connection poles must
never be mixed up. A plus sign and a
minus sign are marked on the
respective poles. The minus pole is
connected greased and well tightened.
