Repair instructions
The electro-mechanical
sterndrive tilting device,
model 280/285
Repair instructions
Operating failures of the sterndrive tilting device can
be caused either by electrical or mechanical faults.
Below we deal with 2 examples of electrical faults and
1 mechanical fault.
1a. Overheating the electrical motor
Avoid running the sterndrive up and down repeatedly.
Such operation can cause over-heating of the electri-
cal motor. The built-in overheating cut-out switch is
being released when the motor temperature reaches a
certain value. If the over-heating switch has been re-
leased, the electrical motor has to cool down (approx.
½ an hour) before the tilting device can be operated
again.
1b. Burnt electrical motor
If the tilt motor is operated too long after the stern-
drive has reached its top position, the motor can
burn. To avoid this an overload circuit breaker can be
installed on the transom.
NOTE! On sterndrives of later manufacture this over-
load circuit breaker is standard equipment.
Install the overload circuit breaker as follows:
Install the overload circuit breaker (1) on the tran-
som, close to the sterndrive tilting device. Remove
the minus wire (earth), (blue), from the flywheel
housing sufficiently to allow the wire to be connected
to the overload circuit breaker and then back to the
flywheel housing. Cut the wire and connect two ter-
minals (2). Install the minus wire (earth) to the fly-
wheel housing.
