Installation of tail piece and intermediate
flange
Remove the propeller.
Install the gasket between
the tail piece and the thrust
tunnel. Apply a sealant
(polyurethane* or silicon)
between the tail piece and
the gasket and between the
gasket and the thrust tunnel,
and position the tail piece
into the hole in the thrust tun-
nel.
*) e.g. Sikaflex®-240 or Sikaflex®-241.
Grease the hole of the inter-
mediate flange and position
this flange. Grease the
threads of the bolts with ‘out-
board gear grease’ before
inserting and tightening
them.
Check for possible leaks immediately the ship returns to
water.
Final assembly
Grease the propeller shaft
with ‘outboard gear grease’
and install the propeller.
The propeller should run a
minimum of 1.5 mm free of
the thrust tube wall, all
round.
Measure dimension ‘B’ and
calculate dimension ‘A’;
Loosen the lock-screw of the
coupling-bushing. Adjust
dimension ‘A’ and re-tighten
the lock-screw.
Grease the threads of the fas-
tenings bolts with ‘outboard
gear grease’ and install the
electric motor to the interme-
diate flange.
For a first check, turn the pro-
peller by hand, it should turn
easily, whilst being connect-
ed to the output spindle of
the electric motor
.
