  • Lubrication: SH100, SH160, SH240 and SH320 are sealed with an oil bath (EP-90); SH360 and up are fed from an oil tank (API GL-5, SAE 80W-90); SH1000 and SH1400 allow on-water oil change.
  • Hydraulic thrusters are supplied with the hydraulic motor only. Without an original Sleipner hydraulic system the installer must fit an oil filter and an oil cooler keeping oil below 75°C (recommended 40-60°C), a valve with flow and pressure limits within the thruster's capability, and preferably a shock valve set 10% - 15% above the chosen maximum pressure. Sleipner S-Link must be used for thruster control.
  • A crossover valve must be mounted as close as possible to the motor: 3/4" valve on SH400, 1" valve on SH700, SH1000 and SH1400.

Figures from the 2025 user manual. The installation manuals print some different values: SH100 7.8 kg, SH360 heavy duty 360 kg, SH550 "56 kW / 123.45 hp" (as printed), SH700 43.3 kW and 61.3 kg, SH1000 light duty 1000 kg.

  • * Drain port connector must not extend internally beyond 10,5mm from the end face. The drain must be installed – always use the upper drain port for best motor lubrication.
  • Use only parallel threaded adaptors, preferably with soft seal; no plumbing tape, hemp or thread sealant.
  • Pre-fill the motor housing with hydraulic oil before start-up, and keep the motor ports covered until the hoses are connected.

SH1400 610 mm 14 / 24 mm 750 / 1000 mm 900 mm 500 × 398 × 398 mm

The gear leg and propellers must never extend out of the tunnel. Tunnel position, length, deflectors and rounded ends (radius 10% of diameter) follow the same rules as all Sleipner tunnel thrusters; metal hulls need the Sleipner galvanic isolation kit.

  • Gear leg P-mark to port, S-mark to starboard; check propeller clearance dry, then fit with MS Polymer sealant on both gasket faces (not in the bolt holes). Oil or grease the bracket O-rings on SH360 and up. SH1000/SH1400: filler between the tunnel and the motor bracket gasket; thread paste on the bolts where the manual calls for it.
  • Twin propellers: LH to port, RH to starboard. Keyed propellers: approx. 1mm gap to the gear leg; grease only the thread; torque without washer, remove, grease the washer face, refit and fold the tab washer; Loctite 243 or similar on anode screws.
  • SH100 to SH550: grease the shafts with seawater resistant grease, align the holding keys and make sure the motor coupling engages the gear leg holding key by at least 80%. The propeller must turn by hand afterwards.
  • SH700 to SH1400: spider coupling between the hubs, centred through the bracket side openings; the flexible coupling must not be subject to axial load. General bolt torques in the SH700 manual: M8 35 Nm, M10 69 Nm, M12 120 Nm (second table: M12 100Nm, M20 150Nm).
  • SH360 and up: pre-fill the gear leg with API GL-5, SAE 80W-90 (0.4 L SH360/SH400, 0.76 L SH420/SH550, 1 L SH700, 3.3 L SH1000, 3.7 L SH1400); oil container above the waterline by at least 20% of the waterline-to-tunnel-centre distance, oil tube without loops.

The SH700 manual prints the 85 Nm motor bolt torque as "752.31 lb/ft" (as printed); the SH1000/1400 manual gives 62 lb/ft.

Operation

  • Main power on, then the panel; push or move the joystick the way you want the bow/stern to go. Proportional systems follow joystick travel.
  • For manoeuvring and docking only: forward or reverse speed must not exceed 4 knots when used; above about 1-2 kn it has little steering effect.
  • Two panels giving opposite directions at the same time stop the thruster. If it stops giving thrust, stop it at once – running without propeller load damages the drive.
  • Never use near people, animals or objects in the water; switch off the main power before touching any part of the thruster.

Seasonal Service

  • Compartment clean and dry, no water or oil leaks; electrical connections clean and tight; batteries in good condition.
  • Out of the water: check propellers and tunnel for damage, propellers secure (LH/RH correct on counter-rotating models), clean off growth, anti-foul propeller and gear leg – never the anode, rubber seals or propeller shaft.
  • Replace the anode every season or at half eroded, with sealant or thread glue on the screw.
  • Models with an external oil tank: the level must stay constant.
  • Motor runs but no thrust: check propellers and LH/RH fitting, the flexible coupling and the gears. Reduced thrust: clean growth from propeller, gear house and tunnel; check hydraulic oil pressure and levels.
