The areas in which the electric motor
of the bow thruster and the battery are
positioned must be dry and well venti-
lated.
5.1 Preparation
The bow thruster will be delivered fully as-
sembled. Perform the following steps:
• Remove the propeller.
• Remove the motor from the intermediate
flange.
• Remove the intermediate flange from the
tail piece.
The 2 bushes are only required for trans-
port and are now no longer needed.
5.2 Installation tailpiece and intermediate flange
• Ensure that the plastic shim plate (1) has been positioned on the
tail piece.
• Place one packing (2) between the tail piece and the tunnel.
• Apply a sealant (e.g. polyurethane or silicone) between the tail
piece and packing, and between the packing and the tunnel wall.
• Place the tail piece in the hole in the tunnel.
Any extra packings used should be ones capable of justifying the
tail piece.
*) e.g. Sikaflex®-292.
• Grease the hole of the intermediate flange and position this
flange.
• Check dimension ‘H’; it must be between 49 and 54 mm (between
1
15
/
16
” and 2
1
/
8
”).
• If the dimension ‘H’ is less than 49 mm (1
15
/
16
”), fit an additional
gasket between the thrust tunnel and the intermediate flange.
• Check again dimension ‘H’.
*) A suitable grease is VETUS ‘Shipping Grease’, Art. code: VSG.
ENGLISH
• Now fit the intermediate flange permanently to the tail piece and
grease the threads of the bolts with ‘outboard gear grease’*) be-
fore inserting and tightening them.
