Installation of tail piece and intermediate flange
Install one (1) gasket between
the tail piece and the thrust
tunnel. Apply a sealant (poly-
ure-thane* or silicon)
between the tail piece and
the gasket and position the
tail piece into the hole in the
thrust tunnel.
*) e.g. Sikaflex®-292.
Grease the hole of the inter-
mediate flange and position
this flange. Check dimension
'H'; it must be between 32
and 35 mm (between 1.26"
and 1.38").
If the dimension 'H' is less
than 32 mm (1.38"), fit an
additional gasket between
the thrust tunnel and the
intermediate flange. Check
again dimension 'H'.
Apply a sealant between the
gasket of the tail piece and
the wall of the thrust tunnel.
Now fit the intermediate
flange permanently to the tail
piece and grease the threads
of the bolts with 'outboard
gear grease' before inserting
and tightening them.
Check for possible leaks immediately the ship returns to
water.
Insert the hose pillar into one
of the threaded holes. Blank
off the other threaded hole by
means of the blind plug sup-
plied. Apply a thread sealant
when fitting the hose pillar
and the blind plug, but not
excessively, so as to prevent
the sealant from getting into
the tail piece itself.
If you wish, the tail piece may
now be filled, as far as practi-
cable, with the gear oil.

Final assembly

Check again dimension 'H'.
Make sure that the key (1)
is properly positioned in
the keyway of the shaft.
Grease the shaft with 'out-
board gear grease' and
install the propeller (2)
with the lock washer (3)
and the hexagonal nut (4).
Secure the nut by bending
the tag of the washer. Fit
the zinc anode (5) to the
propeller shaft by means of the bolt (6).
The propeller should be at least
1.5 mm free of the thrust tube wall,
all round.
Grease the input shaft with an instal-
lation compound, like 'Molykote®
G-n plus'.
Fit the flexible coupling to the input
shaft of the tail piece and secure the
coupling with the locking screw.
Grease the shaft of the electric
motor with an installation com-
pound, like 'Molykote® G-n plus'.
Grease the threads of the fastenings
bolts with 'outboard gear grease'
and install the electric motor to the
intermediate flange.
For a first check, turn the propeller
by hand, it should turn easily, whilst
being connected to the output shaft
of the electric motor.
Install the oil tank and
connect it to the hose
pillar. Fill the tank
completely with oil
(outboard gear oil EP
90).
