Ensure that you operate with high-quality batteries intended for maritime use. • All Sleipner proportional thrusters will work well with Lithium batteries, as the included PPC unit will control the output voltage to safe levels for the thruster. (NB: Ensure you have the latest embedded software installed. The fi rmware version of the Proportional Power Controller (PPC) must be of version 1.033 or later if the PPC is connected to a lithium battery). -

Page 5: Positioning Of The Tunnel / Thruster
Positioning of the tunnel / thruster MC_0003 1. Aim to install the thruster as far forward as possible Due to the leverage effect around the boats’ pivot point. The distance difference from the boat pivots’ point to the thruster will determine the amount of real rotation power for the boat. -
Page 6: Tunnel Length
Tunnel Length MC_0003 Optimal tunnel length Achieving the correct tunnel length depends on many factors from the hull type, operation and environmental conditions. Tunnels should avoid being longer than 4 x the tunnel diameter as this will reduce thruster performance. (NB: Installing long length tunnels can flex/ bend over time and may require additional support. -
Page 7: Tunnel Installation In Sailboats
Tunnel installation in Sailboats MC_0003 Some sail boats have a flat bottom and shallow draft in the bow section. This can make installing the thruster as far forward from the boats main pivot point diffi cult. However, it is possible to install a tunnel thruster in most sail boats, even when the hull does not directly support the fi tting of a tunnel. Instead fi t the tunnel halfway into the underneath section of the existing hull. -
Page 8: Water Deflection
Water Deflection MC_0003 A possible problem in sail boats or fast powerboats is that a non-rounded surface can generate drag from the back face of the tunnel, as it creates a “flat” area facing the flow of water. This problem can be solved in two different ways, depending on what is possible or easier to perform. The best solution which generally reduces the most drag is to make a recess in the hull at the back of the tunnel. -
Page 9: Tunnel Ends
This “free” extra thrust in optimal installations be 30 - 40% of the total thrust. (NB: A Sleipner thruster propeller does not produce cavitation at working speed. Therefore, any cavitation and cavitation noise in the tunnel will be caused during improper tunnel installation.) -
Page 10: Tunnel Installation
Tunnel Installation MC_0003 The following are only general instructions and do not explain in any way the details of fi breglass work. Problems caused by faulty installation of the tunnel, are the installers full responsibility. Seek a professional boat builder when modifying the hull. Find the position in the boat considering the information earlier in this manual and the applicable measurements for the thruster model you are installing. - Page 11 You must apply gel coat to areas you have grounded/ moulded to make waterproof. These areas allow water access to the hull which is typically not waterproof without these applications outside. (NB: All original Sleipner tunnels are fully waterproof when delivered except in the areas where you have cut and bonded it to the hull.)

Gear Leg & Motor Bracket Installation MC_0001 Please refer to the graphic for special considerations relating to your model Mark the tunnel centreline and the boat’s centreline. (NB: Install the gear leg and propeller as shown for the thrust direction to correspond with the control panel. - Page 14 Gear Leg & Motor Bracket Installation MC_0001 Please refer to the graphic for special considerations relating to your model Place the gear leg (without the propeller) with the gasket on inside the tunnel. Place the propeller on the gear leg (NB: Do not secure the propeller with securing parts) to ensure it is centred and rotates freely with the same clearance from each blade to the tunnel wall.
- Page 15 Gear Leg & Motor Bracket Installation MC_0001 Please refer to the graphic for special considerations relating to your model 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). Use appropriate sealant to ensure that no leakages occur.

Motor Installation MC_0019 Please refer to the graphic for special considerations relating to your model Install the motor onto the motor bracket ensuring the couplings are engaged together correctly (top and bottom). (NB: The motor can be placed in all directions on the motor bracket. However, ensure the cable terminals are accessible for electrical installation later.) If you are installing the motor at an angle of more than 30 degrees off vertical, the motor will require separate/ additional support. -
