For electric motor thrusters

• 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)

• When installing the thruster electric motor in small compartments, ensure the compartment is dry and well ventilated to allow for cooling of the electric 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 leg must be outside the tunnel.

• The electric motor, components and cables must be mounted so they remain dry at all times.

• Do not  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 electric 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  re hazard and can cause undesired short-

circuiting.

• Do not lift it by internal cable connections, main terminals.

• The thruster power supply circuit must include the recommended sized fuse and a battery isolation switch.

• The electric/ hydraulic motor must be handled with care. Do not rest the thruster motor on its drive shaft as its weight can damage the shaft.

MC_0425

For thruster systems

• 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.

• We advise painting the gear house and propellers with anti-fouling. (NB: Do not paint the anodes, sealing, rubber ﬁ ttings or propeller shafts)

• There is only room for a thin coat of primer and two layers of anti-fouling between the tunnel and the props.

• Never run the thruster out of water without load.

MC_0501

Lithium Batteries for on/off thrusters models SR, SE and SE-IP

• High capacity lithium batteries are capable of supplying a higher operating voltage to the thruster than SR, SE and SE-IP thrusters are rated for. Running thrusters at higher than rated voltage will reduce operating time, increase wear and damage the thruster. Operating the thruster

outside speci ed ratings will void warranty.

Positioning of the tunnel / thruster

Aim to install the thruster as far forward as possible (1)

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.

Aim to install the thruster as deep as possible under the waterline (2)

Deeper installations prevent air from being sucked into the tunnel from the surface, resulting in reduced thrust performance and increase noise levels

during operation. Deeper installations increase water pressure for maximum ef ciency from the thruster.

The centre of the tunnel should be a minimum of 1 x the tunnel diameter below the waterline. The installer must make evaluations based on thruster

performance, boat type and operating conditions. As a general recommendation, the position of the tunnel should not be a minimum of 1/4 of the

diameter of the tunnel from the boat keel. (NB: This can be overlooked depending on the installation methods deﬁ ned in this manual.)

Tunnel Length

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. Consult with a naval architect.)

1. Do not allow the variable length of the tunnel walls to vary in length excessively. EG. The top tunnel wall is x 4 longer than the bottom wall.

2. If the tunnel is too long, the friction inside will reduce the water speed and thereby the thrust.

3. If the tunnel is too short (typically only in the bottom section of the tunnel) cavitation problems can occur as water flow will not be able to “straighten” itself before reaching the propeller. This cavitation will reduce performance and increase noise during operation.

Thruster within the tunnel

It is important the propellers and the lower unit/ gear leg must be entirely inside the thruster tunnel. Propellers that protrude from the tunnel will not

perform as intended.

4. Standard Use Tunnel length must be long enough to ensure the propellers are not extruding the tunnel.

5. Flat Bottom Hull Tunnel lengths must be longer than the standard measurement outlined within the manual to ensure a circular vacuum is not created between the thruster and the bottom of the boat.

6. High-Speed Boats Tunnel lengths must be increased to protect the propeller from damage when crashing against the water surface during high-speed cruising. (NB:

This can include the length of a spoiler)

Tunnel installation in Sailboats

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 dif cult. (Fig. 1).

However, it is possible to install a tunnel thruster in most sail boats, even when the hull does not directly support the  tting of a tunnel.

Instead  t the tunnel halfway into the underneath section of the existing hull. Strengthen it with a deflector/ spoiler directing the water flow around

the tunnel. This will allow installation of the thruster in the proper position on the boat, maintaining the reliability and space advantages of the tunnel thruster.

This installation is being used by some of the world’s largest sail boat builders and has proven to give little to no speed loss during normal cruising. This can also be an installation method for flat bottomed barges to avoid extremely long tunnels and large oval tunnel openings in the hull.

Water Deflection

1. 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.

2. The best solution which generally reduces the most drag is to make a recess in the hull at the back of the tunnel. As the back face is removed

water can flow freely past the tunnel entry. The depth and shape of this recess will depend on the boat and the angle facing up/ down aft of the

tunnel insert. Normally it is angled slightly down because of the water flow on this area.

3. Making a deflector/ spoiler in front and underneath the tunnel can also reduce damage to the thruster and drag. The deflector/ spoiler will push the water flow out from the hull so water can pass by the back face of the tunnel. The shape and size of this deflector/ spoiler will depend on the hull shape. The easiest way of making the deflector/ spoiler is to retain a part of the lower forward area of the tunnel while installing the tube. Use this area as support to mould a soft curve/spoiler shape from the hull.

4. The thruster propeller can spin (passively) producing noise while sailing or cruising as water is forced through the tunnel. Water-flow directed through the tunnel at high speeds, during turning or as the boat bumps waves while underway can also damage the thruster.

(NB: As a rule, you should not see the back face of the tunnel when standing directly in front of the boat looking aft.)

To protect the propeller from water entering into

the tunnel at high speeds (25 knots +) the

extended deflector/ spoiler must provide

protection from the front and the bottom. In the

event when the boat is traveling at high speeds it

will commonly pound upon the water surface.

Tunnel Ends

Rounded tunnel ends will maximise thrust and minimise noise and cavitation.

For best performance round the tunnel connection to the hull-side as much as possible. The minimum rounding has a radius of 10% of the diameter of the tunnel.

Signi cant advantages of a rounded tunnel over a sharp tunnel to hull connections are:

1. A rounded tunnel end will prevent the creation of turbulence/ cavitation created from a sharp tunnel end when water passes by the tunnel.

- The turbulence/ cavitation will block the outer area of the tunnel and thereby reduces the effective tunnel diameter and thrust.

- Turbulence/ cavitation on the propeller will lessen the thrusters performance and create excess noise.

2. For steel/ aluminium hulls angled tunnel ends also offer similar performance as a rounded connection.

3. A rounded tunnel end makes the thruster draw water from along the hull-side, creating a vacuum that will suck the boat sideways and thereby give

additional thrust.

- With a sharp tunnel end, the thruster will be unable to take water from along the hull-side, and you will not gain the desired vacuum and

additional thrust. 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.)

Tunnel Installation

IMPORTANT

We recommend that a professional does the  breglass, steel or aluminium  tting of the tunnel. These instructions are only general instructions and

do not explain in any way the details of  breglass work. Problems caused by faulty installation of the tunnel, are the installers full responsibility.

1. Find the position in the boat considering the information earlier in this manual and the applicable measurements for the thruster model you are installing. Mark the centre of the tunnel on both sides of the hull. Drill a hole horizontally at these marks.

2. Mark the circle for the tunnel opening (outside diameter of the tunnel) and cut the hole.

3. Grind off the gel coat to the “real  breglass” area 12cm around the hole on both inside and outside the hull to cast the tunnel to the hull (Fig. 3).

4. Insert the tunnel and mark its shape to  t the hull. (NB: if you are installing with a deflector/ spoiler, leave a part of the tunnel in the front and

underside of the tunnel that will cover the back face.)

5. Cut the tunnel ends to the desired shape and lightly sand its surface. Clean the area with acetone or similar where you are going to apply

 breglass. (NB: Do not cast or add ﬁ breglass to the area were the thruster will be placed.)

6. Cast the tunnel to the inside of the hull, use at least eight layers of 300g  breglass and resin, preferably alternating mat and rowing types of  breglass. To round the tunnel ends to a 10% radius make further layers inside to preserve the desired hull thickness.

(NB: Ensure gaps between the tunnel and the hull are completely ﬁ lled with resin/ ﬁ breglass. In areas where you can not access to make layers of resin/ ﬁ breglass, a resin/ ﬁ breglass mixture must be used in that area.)

Tunnel Installation

With tunnel installed and cast.

1. Round the edges with a radius of 10% of the tunnel diameter.

2. For steel/ aluminium hulls make a slope with a length of 10-15% of the tunnel diameter.

(NB: If this is not possible, round the tunnel end as much as possible.)

3. Additionally cast two layers on the outside of the tunnel/ hull in a 10cm area

4. Follow the same method if making the deflector/ spoiler.

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.)

IMPORTANT

Avoid all casting where the motor-bracket is to be placed, as this will cause mis t and possible failure to the gear house.

1. Insert the drive pin to the motor drive shaft. Insert the coupling to align with the drive pin in the motor shaft.

2. 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.)

3. If you are installing the motor at an angle of more than 30 degrees off vertical, the motor will require separate/ additional support. (NB: Do not position supports on the motors top cap.)

4. Fasten the bolts holding the motor to the motor bracket with the below torque.

5. Check the drive shafts are engaged by rotating the propeller. (NB: Rotating the propellers can be hard due to the gear reduction and the motor,

however the propeller must be able to rotate via hand power.)

IMPORTANT

The thruster motor assembly must be protected using suitable covering to avoid dust/debris ingress from fabrication/maintenance/shipbuilding

operations. On completion of operations, the cover must be removed before operating the thruster.

Electrical Installation

1. Plan the location of electrical components before starting with the electrical installation. Main electrical components will typically consist of battery, fuse, main switch and thruster motor, see Wiring Diagram chapter for an overview.

Sleipner offers both manual main switches and Automatic Main Switches (AMS). Sleipner AMS is controlled by the control panel in addition to

the option of manual operation. Turning on the control panel also turn on the automatic main switch. When the control panel is turned off the automatic main switch is turned off. This ensures that the control electronics and motor are only energized when the control panel is turned on.

Sleipner offers AMS supporting either S-Link or ON/OFF control panels. Note that the AMS requires a separate power supply which should be

protected by a dedicated fuse. Ensure to select an AMS with a voltage rating according to the chosen motor- and battery voltage.

Electrical products installed in gasoline engine spaces or other areas potentially exposed for explosive gases must be Ignition Protected.

Products installed in such locations should conform to the ISO 8846, SAE J1171 or UL 1500 standard.

Common ground connection is required for dual thruster installations with two battery banks.

2. Estimate the total length of the power cables to determine the recommended cross-section. The total power cable length is de ned as the

distance from the positive battery terminal, via fuse, main switch, and thruster motor, and all the way back to the negative battery terminal.

3. Find the recommended power cable cross-section for the installation by using the estimated total power cable length and the table shown in the chapter Electrical Reference Guide.

4. Select the recommended fuse size by using the table shown in the chapter Electrical Reference Guide.

5. Use an appropriate dimensioned battery with Cold Cranking Amps (CCA) according to recommendations given in the Electrical Reference Guide

chapter. Battery voltage must be compliant with the voltage rating of the thruster motor and control circuitry. The capacity and rated discharge current of the battery should be according to the rated nominal current drawn and the typical duty cycle for thruster operation. The nominal current drawn is listed in the Electrical Reference Guide chapter.

The actual voltage at the motor while running the thruster determines the motor RPM and thrust. Using a smaller cross-section than

recommended or a low-capacity battery could reduce performance.

MC_0143

Installing a battery close to the thruster reduces the length of the power cables and potentially increases the performance, due to lower voltage

drop in the power cables. For installations on large vessels with bow and stern thrusters or catamarans a dedicated battery for each thruster should be considered.

6. Install and connect the electrical components according to the applicable Wiring Diagram chapter.

For safety reasons it is always recommended to install a fuse and a main switch on the power cables and as close as possible to the positive

battery terminal. The main switch must be installed such that it is easily accessible so that the thruster can be electrically disconnected to a safe state when not on-board or in the case of an emergency.

For dual thruster systems using only one battery bank a dedicated fuse and main switch should be installed for each thruster. These should be

installed close to the battery bank.

Follow the instructions in the Motor Lug Connection chapter when fastening the power cables to the motor.

7. Fuse and main switch should be installed according to the installation manual accompanying the products.

8. Install the control panel according to the instructions in the Installation Guide included with the control panel.

WARNING

After all electrical connections have been completed, turn off main switch and check the following with an ohmmeter:

1. There is no electrical connection between motor flange and the positive terminal on the motor.

2. There is no electrical connection between motor flange and the negative terminal on the motor. If unsure contact skilled personnel.

MC_0024

1. Sleipner Motor AS (The “Warrantor”) warrants that the equipment (parts, materials, and embedded software of products) manufactured by the Warrantor is free from defects in workmanship and materials for purpose for which the equipment is intended and under normal use and maintenance service (the “Warranty”).

2. This Warranty is in effect for two years (Leisure Use) or one year (Commercial and other Non-leisure Use) from the date of delivery/purchase by the end user, with the following exceptions;

(a) For demonstration vessels, or vessels kept on the water, the dealer is considered as the end user from 6 months after their launch of the

vessel;

(b) The warranty period starts no later than 18 months after the  rst launch of the vessel.

Please note that the boat manufacturer and dealer must pay particular attention to correct maintenance and service both by the products

manuals as well as general good practice for the location the boat is kept in the period the boat is in their care. In cases where the 6 and 18 months grace periods for boat builders and dealers are passed, it is possible to obtain a full warranty upon inspection and approval of the warrantor or such representative.

3. Certain parts, classi ed as wearable or service parts, are not covered by the warranty. A failure to follow the required maintenance and service work as described in the product manual render all warranty on parts or components directly or indirectly affected by this void. Please also note that for some parts, time is also a factor separately from actual operational hours.

4. This Warranty is transferable and covers the equipment for the specied warranty period.

5. The warranty does not apply to defects or damages caused by faulty installation or hook-up, abuse or misuse of the equipment including

exposure to excessive heat, salt or fresh water spray, or water immersion except for equipment specically designed as waterproof.

6. In case the equipment seems to be defective, the warranty holder (the “Claimant”) must do the following to make a claim:

(a) Contact the dealer or service centre where the equipment was purchased and make the claim. Alternatively, the Claimant can make the

claim to a dealer or service centre found at www.sleipnergroup.com. The Claimant must present a detailed written statement of the nature

and circumstances of the defect, to the best of the Claimant’s knowledge, including product identi cation and serial nbr., the date and place of

purchase and the name and address of the installer. Proof of purchase date should be included with the claim, to verify that the warranty period has not expired;

(b) Make the equipment available for troubleshooting and repair, with direct and workable access, including dismantling of furnishings or similar,

if any, either at the premises of the Warrantor or an authorised service representative approved by the Warrantor. Equipment can only be returned to the Warrantor or an authorised service representative for repair following a pre-approval by the Warrantor’s Help Desk and if so, with the

Return Authorisation Number visible postage/shipping prepaid and at the expense of the Claimant.

7. Examination and handling of the warranty claim:

(a) If upon the Warrantor’s or authorised service Representative’s examination, the defect is determined to result from defective material or

workmanship in the warranty period, the equipment will be repaired or replaced at the Warrantor’s option without charge, and returned to the Purchaser at the Warrantor’s expense. If, on the other hand, the claim is determined to result from circumstances such as described in section 4 above or a result of wear and tear exceeding that for which the equipment is intended (e.g. commercial use of equipment intended for leisure use), the costs for the troubleshooting and repair shall be borne by the Claimant;

(b) No refund of the purchase price will be granted to the Claimant, unless the Warrantor is unable to remedy the defect after having a reasonable
