a) Lower and raise the turbine to determine correct position of the hull closing plate so
that it fits evenly and squarely in the rebate in the hull, then tighten the hose clamps
(delivered with unit). The closing plate must rest evenly on its gasket, with pressure so
that no upwards movement of the plate is possible even in heavy sea conditions when
the hull is subjected to slamming forces.
b) Once the hull closing plate adjustment has been completed, adjust the "up" position
detector and tighten its grub screw with a 2.5 mm Allen key. This should be done with
the unit fully retracted.
c) Note that the down position detector is pre-adjusted (before leaving the factory) and
should not be touched.
d) If re-adjustment is necessary, care should be taken to re-adjust the detector so that
adjustment nuts do not touch the motor support when fully down and that the
detector grub screw (2.5mm Allen key screw) is tightened down after re-adjustment.
e) The thrust plate should not protrude from the mounting base, since it absorbs the
horizontal stresses when thrusting or manoeuvring. If protruding, adjust the down
position detector as described above.
