Repair instructions
4. Hang the hose clamp for the rubber bellows of the
universal joint on the "neck" of the gear housing.
Grease the splines of the universal joint and those of
the shaft with grease. Push the sterndrive gently
against the drive shaft. Turn simultaneously the uni-
versal joint to allow the shaft splines to find the corre-
sponding female splines of the joint more easily.
NOTE! Be careful during the assembly not to damage
either splines thus making the mating more difficult.
Install the two plastic bushings (2, figure under point
1) in the holes of the suspension yoke. Grease the
shaft journals (4) with grease or Molycote.
Insert the sterndrive suspension yoke into the tran-
som shield and align it to allow the shaft journals to
be pushed into the holes of the yoke. Turn the shaft
journals to allow the locking screws (5) to be in-
stalled. Tighten the locking screws.
5. Attach the universal joint bellows to the sterndrive.
Locate the hose clamp in such a way that its tighten-
ing screw (1) ends up on the underside of the bel-
lows. Check to make sure that the bellows is correct-
ly installed and tighten the clamp. Use a flexible
screwdriver, special tool 884573.
Tighten the clamp so as to avoid water leaking into
the boat. Hang on the hose clamps for the exhaust
bellows and the cooling water hose. The tightening
screw on the cooling water hose must be located two
o'clock of the hose (2).
The tightening screw for the exhaust bellows must be
turned pointing at 6 o'clock, (3). The picture reflects
the correct positioning of the hose clamps.
Test by turning the sterndrive from one side to the
other and check thereby that the clamps do not
interfere with the sterndrive nor that they chafe
against and thus damage close by hoses.

6a. Sterndrives of later manufacture:
Lower the steering helmet and grease the 'attachment
bolt' with grease. Turn the recessed holes facing
outwards.
Then push home the 'attachment bolt' into the helmet
and center it so that the two Allen-head screws can be
tightened.
Tightening torque: 35 Nm (26.25 lb.ft.).
Prior to the tightening, grease the threads of the
screws with grease. In order to be able to turn and
center the 'attachment bolt' screw holes, the screws
must be installed in the holes marked (1). Then the
'attachment bolt' can be turned.
6b. Sterndrives of earlier manufacture:
Lower the steering helmet and tighten the tapered
locking screw (6) in figure under point 3, in the upper
gear housing.
Tightening torque: 50–60 Nm (37.5–45 lb.ft.).
Install the locking plate (7) in figure under point 3, for
the shift cable in a way that it is locking in the groove
of the cable.
