Installation of tail piece and intermediate flange
Install one (1) gasket
between the tail piece and
the thrust tunnel. Apply a
sealant (polyure-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 49
and 54 mm (between 1.93"
and 2.13").
If the dimension 'H' is less
than 49 mm (1.93"), 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
supplied. Apply a thread
sealant when fitting the hose
pillar and the blind plug, but
not excessively, so as to pre-
vent the sealant from getting
into the tail piece itself.
If you wish, the tail piece may now be filled, as far as practica-
ble, 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
'outboard 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
installation compound,
'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 fasten-
ings bolts with 'outboard gear
grease' and install the electric
motor to the intermediate flange.
Use one of these bolts to fasten the
relay support as well.
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 com-
pletely with oil (outboard
gear oil EP 90).
