Gear Leg & Motor Bracket Installation
!
Please refer to the graphic for special considerations relating to your model
!
EN
1. Mark the tunnel centreline and the boat’s centreline.
(NB: Install the gear leg and propeller as shown above for the thrust direction to correspond
with the control panel.)
2. Use the gasket or template (recommended) to mark the hole centres and double-check the measurements. One hole MUST be placed using
the boat centreline as shown above.
(NB: All holes must be in-line with the tunnels’ centreline for correct installation, clearance between the
propeller and the tunnel is minimal.)
3. Smooth the surface of the tunnel. A rough surface will cause possible failure/ movement of the gear leg. The motor bracket must rest steadily on
the tunnel.
4. Drill the main centre hole followed by the two screw-holes.
5. Place the gear leg (without the propeller) with the gasket on inside the tunnel. Place the propeller on the gear leg to ensure it is centred and
rotates freely with the same clearance from each blade to the tunnel wall. Place top motor bracket to measure the drive shaft has come through
the motor bracket at the correct height. Remove the gear leg and propeller for fi nal installation.
6. Apply appropriate sealant to both sides of the gasket and place on the gear leg. Place the gear leg in the tunnel (without the propeller).
7. Install the top motor bracket and gear leg gently together. Use appropriate sealant to ensure that no leakages occur.
(NB: See your sealant data
sheet for the correct application process.)
8. Fasten the gear leg and the motor bracket with the bolts provided. Tighten to torque as shown above.

Bow Installation Considerations and Precautions
EN
• The thruster must NOT be installed in compartments that require ignition proof electric equipment. If necessary, make a separate compartment.
(NB: Ignition Protected systems are tested to be installed in areas with possible explosive gases in accordance with ISO 8846)
• The electro motor will generate some carbon dust so any storage compartments must be separated from the thruster to prevent nearby items
becoming dusty/ dirty.
(NB: IP version motors generate dust but are enclosed.)
• When installing the thruster electro motor in small compartments, ensure the compartment is well ventilated to allow for cooling of the electro
motor.
• If the height of the room you are installing the thruster is limited, the thruster can be installed horizontally or at any angle in-between.
- If the electro motor is positioned more than 30 degrees off vertical, it must be supported separately.
- Beware of keeping installation within advised measurements. No part of the propeller or gear house must be outside the tunnel.
• Do not install the thruster in a position where you need to cut a stiffener/ stringer/ support that may jeopardise the hull integrity without checking
with the boat builder this can be done safely.
• The electro motor, components and cables must be mounted so they remain dry at all times.
• We advise painting the gear house and propellers with anti-fouling.
(NB: Do not paint the anodes, sealing, rubber fi ttings or propeller shafts)
• Do not fi nish the inside of the tunnel with a layer of gel-coat/ topcoat or similar. There is only room for a thin coat of primer and two layers of anti-
fouling between the tunnel and the props.
• Don’t install the electro motor close to easily flammable objects or equipment as it will reach over 100°C before the temperature switch is activated.
• Do not store items close to the thruster motor. Any loose items near the thruster motor is a potential fi re hazard and can cause undesired short-
circuiting.
It is the installers responsibility
When installing Sleipner equipment follow the outlined regulations/ classifi cation rules (electrical/ mechanical) according to
international or special national regulations. Instructions in this guide cannot be guaranteed to comply with global electric/
mechanic regulations/ classifi cation rules.
Follow all health and safety laws in accordance with their local outlined regulations/ classifi cation rules.
Before installation, it is important that the installer reads this guide to ensure necessary acquaintance with the product.
The recommendations made in this manual are guidelines ONLY, and Sleipner Motor AS (Sleipner) strongly recommend that before
installation, advice is obtained from a naval architect familiar with the particular vessel and regulations/ classifi cations.
This manual is intended to support educated/ experienced staff and is therefore not suffi cient in all details for professional
installation.
(NB: These instructions are only general instruction. If you are not skilled to do this work, please contact professional
installers for assistance.)
All electrical work must be done by a licensed professional.
Faulty installation of Sleipner products will render all warranty given by Sleipner Motor AS void.

Thruster Installation Considerations and Precautions
EN
Before installation, it is important that the installer reads this guide to ensure necessary acquaintance with this product.
• The electro motor must be handled with care. Do not lift it by internal cable connections, main terminals or placed down on the drive shaft.
• The thruster power supply circuit must include the recommended sized fuse and a battery isolation switch.
• Never run the thruster out of water.
• It is important to follow the guidelines in this manual. Failure can result in severe damage to the thruster.
