SH 240 & SH 320
Positioning of the Retract thruster
EN
MC_0067
The thruster must always be installed so the hatch is opened towards the direction of travel.
Bow
The thruster must be installed as far forward as possible. Allow for 10cm around the thruster for moulding the retract frame and the depth of the
retracted propeller is 185mm (SR 80/100), 250mm (SR 130/210) or 300mm (SR 250/300) under the waterline. For bow installations, the thruster
must be installed in the centre line of the keel.
(NB: Installing the thruster further forward will give less depth for the propeller but offer better
leverage effect for turning.)
Stern
Follow the same depth requirement for the retracted propeller of 185mm (SR 80/ 100), 250mm (SR 130/ 210) or 300mm (SR 250/ 300) under the
waterline. The thruster while retracted must not conflict with any other component of the vessel such as stern drives/ propellers, trim tabs or rudders.
Therefore stern installations do not require to be installed on the hulls keel centre line and can be installed off centre.
Installing the thruster below the waterline as outlined is important for two reasons:
1. So that it does not suck air down from the surface which will reduce performance and increase noise levels.
2. To get as much water pressure as possible to receive maximum effi ciency from the thruster.
Always ensure enough space for the complete SR unit including motor, actuators, retract frame, future service and for installation moulding to the hull.

Technical Specifi cations
EN
Motor:
Hydraulic type (specifi cations above)
.
Gear house:
Seawater resistant bronze. Ball-bearing at propeller shaft and a combination of ball bearing and slide bearing at drive shaft.
Gears:
Hardened precision gears
Lubrication:
Oil bath from tank (gear oil EP 90)
Bearings:
Angular contact ball bearing at propeller shaft and combination of ball bearing and needle bearing at drive shaft.
Motor bracket:
Seawater resistant aluminium, galvanically insulated from the motor.
Tunnel:
Cross spun with rowing G.R.P tunnel
Steel & aluminium tunnels available at request.
Propeller:
5-blade skewback “Q-prop” propeller, fi breglass reinforced composite.
Safety:
Flexible coupling between hydraulic-motor and drive shaft protects gear system if propeller jams.
If using the original Sleipner panel, the panel shuts off automatically 6 minutes after last use.
An integrated microprocessor monitors solenoids, reducing wear and risk of solenoid lock-in. Auto-stop of the thruster in case of
accidental solenoid lock-in or if run signal is continuous for more than 3 minutes
Depending on the panel type after a certain time not in use, the console will shut down and retract the thruster.
(NB: the thruster
will retract automatically when turned off.)
