IDENTIFYING TROLLING MOTOR FEATURES BY THEIR ASSOCIATED CABLES
Your trolling motor may be pre-installed with Built-In MEGA Down Imaging OR Universal Sonar and may include an i-Pilot Link. All of these features require cables to be connected to an output device. These connections are present on the trolling motor and have cables that exit below the Control Head. To better identify cables present, refer to the diagrams below that detail what the Built-In MEGA Down Imaging, Universal Sonar, and i-Pilot Link cable connectors look like.

NOTICE: The i-Pilot system does not have an external wired connection.

If one connection below the Control Head is present, the motor may be equipped with:

i-Pilot and Universal Sonar,
i-Pilot and Built-in MEGA Down Imaging,
ONLY Universal Sonar, or
ONLY Built-in MEGA Down Imaging.

If two connections below the Control Head are present, the motor may be equipped with either:

i-Pilot Link and Universal Sonar or
i-Pilot Link and Built-in MEGA Down Imaging

ROUTING CONNECTION CABLES
Please follow these instructions for routing any and all of the cables present for any of the pre-installed features that may come with your trolling motor. This routing should be followed whether there are one or two connection cables present. If you are unsure of the cables present, please review the “Identifying Trolling Motor Features By Their Associated Cables” section of these Installation Instructions.

1

a. Place the motor in the deployed position.
b. Locate the Built-in MEGA Down Imaging, i-Pilot Link and/or Universal Sonar cable(s), at the base of the Control Head.
CAUTION
Not following the recommended wire routing for the Built-in MEGA Down Imaging, i-Pilot Link, and/or Universal Sonar cable(s), if equipped, may cause damage to the product and void your product warranty. Route cables away from pinch points or other areas that may cause them to bend in sharp angles. Routing the cables in any way other than directed may cause damage to the cables by being pinched or severed.
NOTICE: Universal Sonar connector is shown for illustration purposes.

2

c. The cable(s) should be fed all the way through the Coil Cord. It/they should exit the Coil Cord at the bottom of the Coil Cord, where it connects to the
Mount.

NOTICE: After the cable(s) exit(s) the Coil Cord, it/they should be routed through an established routing system on the boat, in an area with minimal interference. Power cables or other elements that may produce interference for the sonar signals. Inspect the selected route carefully to ensure that there are no sharp edges, obstacles, or obstructions that may damage the cables.

FEATURE OVERVIEW AND CONNECTING THE CABLES
The cable(s) from the Control Head for each feature installed on the trolling motor is connected to an output device separately. Once the features that may be installed are identified, follow the instructions below to ensure the cables are connected correctly.

Built-In MEGA Down Imaging Built-In MEGA Down

Imaging delivers nearly 3X the output of standard Side Imaging ® and takes fishfinding into the megahertz frequency for the very first time. The Minn Kota flagship families of trolling motors, including Ultrex, Ulterra, Terrova, and Fortrex, now include Built-In MEGA Down Imaging sonar, the clearest imaging available only from Humminbird. With Humminbird MEGA imaging sonar built right into the trolling motor, you now have a crystal clear view of what’s directly beneath the boat, without having to manage all of the cables that come with external transducers. The Built-In MEGA DI transducer is only available on new models equipped from the factory and cannot be added to an existing trolling motor.
The Built-in MEGA DI transducer will provide both MEGA Down Imaging and 2D CHIRP Digital Sonar to select Humminbird models. All Built-In MEGA DI trolling motors will come “Apex and Solix Ready” out of the box. An adapter cable accessory (MKR-MDI-1 1852085 or MKR-MDI-2 1852086) is available for purchase that will allow the connection of any compatible Humminbird Helix fish finder. The MKRMDI-1 is used on Helix 8, 9, 10, 12 and 15 models. The MKR-MDI-2 is used for Humminbird Helix 7 models only. See the Built-In MEGA Down Imaging Compatibility chart online.

NOTICE: You can only view Down Imaging with a MEGA DI or MEGA SI HELIX G2N, G3N or G4N Series model and a required adapter, or with any SOLIX or APEX Series model. The built-in transducer cannot supply MEGA Imaging to Humminbird models that do not already have the capability. If you have a G2/G2N, G3/G3N HELIX that is not a MEGA SI or MEGA DI model, you will still get 2D Dual Spectrum CHIRP Sonar from the transducer. SOLIX G1 and HELIX G2 and G2N units need to be running the latest software update to view sonar from motors with Built-In MEGA imaging. You can get the latest version of the software for your fish finder on humminbird.com. Built-In MEGA Imaging is not supported by HELIX G1 models or other brands of fish finders.

a. Place the motor in the deployed position.
b. The Built-In MEGA Down Imaging connector from the Control Head is a 14 pin connector. Built-In MEGA Down Imaging may be installed on its own, or in conjunction with an i-Pilot or i-Pilot Link system. It will never be installed with Universal Sonar. Locate and identify the correct connection for Built-in MEGA Down Imaging cable(s), at the base of the Control Head.
NOTICE: Built-in MEGA Down Imaging is always paired with either i-Pilot or i-Pilot Link on Terrova, Ulterra and Ultrex motors. It may be pre-installed on a Fortrex motor without other features that require external connections.

NOTICE: Critical cable routing for 60″ and 72″ motors with i-Pilot Link and Built-in MEGA Down Imaging. Accessory Cables must exit the Coil Cord leaving three or more open coils between where the cables exit and the motor base; as assembled by the factory. Routing the cables in any other manner will not allow the motor to stow properly.

c. When installing with a Solix or Apex, the BuiltIn MEGA Down Imaging cable can be plugged directly into the Solix fish finder. Plug the Built-in MEGA Down Imaging cable into the corresponding connection the Solix fish finder.
d. When installing with a Helix, first attach the AdapteCable and then plug the Adapter Cable into the Helix fish finder. The Adapter Cable will only have one connection that is keyed on the back of the Helix fish finder. Plug the Adapter Cable into the only matching keyed connection.
NOTICE: Check for compatibility or any required adapter cables online at minnkotamotors.com. The cable from the trolling motor can be extended with a 10’ Extension Cable #720081-1 or the 30’ Extension Cable #720081-2 found at humminbird.com.
NOTICE: If any cables need to be routed, please follow the guidelines in the Routing Connection Cables section of these installation instructions.

NOTICE: The connectors are keyed to prevent reversed installation.

Universal Sonar
Your trolling motor may be pre-installed with a Universal Sonar transducer system. Universal Sonar is a 2D sonar transducer with a temperature sensor that is integrated into the lower unit of the trolling motor. It has an operating frequency of 83/200 kHz. Connecting this transducer to a compatible fishfinder gives you a 2D sonar view of what is happening directly below your trolling motor. The integrated design protects the transducer from underwater hazards and prevents tangles and damage to the transducer cables.
All Universal Sonar motors are equipped with an internal bonding wire, incorrect rigging will cause sonar interference and can damage your trolling motor, electronics, and other boat accessories. To minimize trolling motor interference, ensure that the fish finder and trolling motor are powered by separate batteries. Please refer to the Battery & Wiring Installation and Motor Wiring Diagram sections of this manual for correct rigging instructions.
The Universal Sonar Cables are shielded to minimize interference. To protect this shielding the cables should not be pulled tight against sharp angles or hard objects. If using cable ties, do not over-tighten. Any excess cable should be bundled in a loose loop of no less than 4” in diameter. In certain situations, air bubbles may adhere to the surface of the Universal Sonar transducer, and affect the performance. If this happens simply wipe the surface of the transducer with your finger.

NOTICE: Universal Sonar does not support imaging screens that require higher frequencies such as 455 kHz or 800 kHz (Down Imaging, Side Imaging, etc.). Down Imaging (DI) specific units are not compatible with Universal Sonar. See the compatibility chart for a list of compatible fish finders at minnkotamotors.com.
The connector for Universal Sonar exits the trolling motor below the Control Head and consists of a 4-pin plug. An adapter cable (MKR-US2) that is sold separately is required for all installations. For a current list of compatible fish finders and the correct adapter cable, or more information on Universal Sonar, please visit minnkotamotors.com.

i-Pilot Link
i-Pilot Link allows your Minn Kota trolling motor and Humminbird to communicate with each other to change the way you fish. i-Pilot Link delivers a large array of GPS capabilities including controlling speed, steering, Spot-Lock, and the ability to record and retrace paths on the water, all at your fingertips. To learn more about the GPS capabilities available with your i-Pilot Link navigation system, please refer to the Owner’s Manual by visiting minnkotamotors.com.

NOTICE: The i-Pilot Link system needs an external wired connection. The i-Pilot system does not need an external wired connection.

The i-Pilot Link remote and controller make up the i-Pilot Link navigation system. The i-Pilot Link remote comes paired to the controller from the factory. The i-Pilot Link controller contains a very sensitive compass and is where all GPS satellite and i-Pilot Link remote signals are received. The i-Pilot Link controller is contained in the trolling motor Control Head and is connected to a fish finder from a connection cable that exits the Control Head.
The Ethernet cable for the i-Pilot Link system has an 8-pin connector. The i-Pilot Link system can be connected directly to the Humminbird or to the Humminbird Ethernet Switch (optional). If you purchase an Ethernet Switch, install it using the instructions included in the Ethernet Installation Guide. The Ethernet Extension Cable is optional for your installation.

BATTERY and WIRING INSTALLATION

BOAT RIGGING & PRODUCT INSTALLATION
For safety and compliance reasons, we recommend that you follow American Boat and Yacht Council (ABYC) standards when rigging your boat. Altering boat wiring should be completed by a qualiﬁ ed marine technician. The following speciﬁ cations are for general guidelines only:

CAUTION
These guidelines apply to general rigging to support your Minn Kota motor. Powering multiple motors or additional electrical devices from the same power circuit may impact the recommended conductor gauge and circuit breaker size. If you are using wire longer than that provided with your unit, follow the conductor gauge and circuit breaker sizing table below. If your wire extension length is more than 25 feet, we recommend that you contact a qualiﬁ ed marine technician.
CAUTION
An over-current protection device (circuit breaker or fuse) must be used. Coast Guard requirements dictate that each ungrounded current-carrying conductor must be protected by a manually reset, trip-free circuit breaker or fuse. The type (voltage and current rating) of the fuse or circuit breaker must be sized accordingly to the trolling motor used. The table below gives recommended guidelines for circuit breaker sizing.
CONDUCTOR GAUGE AND CIRCUIT BREAKER SIZING TABLE
This conductor and circuit breaker sizing table is only valid for the following assumptions:

No more than 2 conductors are bundled together inside of a sheath or conduit outside of engine spaces.
Each conductor has 105° C temp-rated insulation.
No more than 5% voltage drop allowed at full motor power based on published product power requirements.

Reference
United States Code of Federal Regulations: 33 CFR 183 – Boats and Associated Equipment ABYC E-11: AC and DC Electrical Systems on Boats

SELECTING THE CORRECT BATTERIES
The motor will operate with any lead acid, deep cycle marine 12-volt battery/batteries. For best results, use a deep cycle, marine battery with at least a 105 amp-hour rating. Maintain battery at full charge. Proper care will ensure having battery power when you need it, and will significantly improve the battery life. Failure to recharge lead-acid batteries (within 12-24 hours) is the leading cause of premature battery failure. Use a multi-stage charger to avoid overcharging. We offer a wide selection of chargers to fit your charging needs. If you are using a crank battery to start a gasoline outboard, we recommend that you use a separate deep cycle marine battery/ batteries for your Minn Kota trolling motor. For more information on battery selection and rigging, please visit minnkotamotors.com. Minn Kota trolling motors can run on Lithium Ion batteries. However, they are specifically designed to run on traditional lead acid batteries (flooded, AMG, or GEL). Lithium Ion batteries maintain higher voltages for longer periods of time than lead acid. Therefore, running a Minn Kota trolling motor at speeds higher than 85% for a prolonged period could cause permanent damage to the motor.

WARNING
Never connect the (+) and the (–) terminals of the same battery together. Take care that no metal object can fall onto the battery and short the terminals. This would immediately lead to short and extreme fire danger.
CAUTION
Refer to “Conductor Gauge and Circuit Breaker Sizing Table” in the previous section to find the appropriate circuit breaker or fuse for your motor. For motors requiring a 60-amp breaker, the Minn Kota MKR-19 60-amp circuit breaker is recommended.
CAUTION
Please read the following information before connecting your motor to your batteries in order to avoid damaging your motor and/or voiding your warranty.
ADDITIONAL CONSIDERATIONS
Using Alternator Chargers
Your Minn Kota trolling motor may be designed with an internal bonding wire to reduce sonar interference. Most alternator charging systems do not account for this bonding wire and connect the negative posts of the trolling motor batteries to the negative posts of the crank/starting battery. These external connections can damage connected electronics and the electrical system of your trolling motor, voiding your warranty. Review your charger’s manual carefully or consult the manufacturer prior to use to ensure your charger is compatible. Minn Kota recommends using Minn Kota brand chargers to recharge the batteries connected to your Minn Kota trolling motor, as they have been engineered to work with motors that include a bonding wire.

Additional Accessories Connected to Trolling Motor Batteries
Significant damage to your Minn Kota motor, your boat electronics, and your boat can occur if incorrect connections are made between your trolling motor batteries and other battery systems. Minn Kota recommends using an exclusive battery system for your trolling motor. Where possible, accessories should be connected to a separate battery system. Radios and sonar units should not be connected to any trolling motor battery systems as interference from the trolling motor is unavoidable. If connecting any additional accessories to any trolling motor battery system, or making connections between the trolling motor batteries and other battery systems on the boat, be sure to carefully observe the information below.
The negative (-) connection must be connected to the negative terminal of the same battery that the trolling motor negative lead connects to. In the diagrams below this battery is labeled “Low Side” Battery. Connecting to any other trolling motor battery will input positive voltage into the “ground” of that accessory, which can cause excessive corrosion. Any damage caused by incorrect connections between the battery, systems will not be covered under warranty.
Automatic Jump Start Systems and Selector Switches
Automatic jump start systems and selector switches tie the negatives of the connected batteries together. Connecting these systems to the “High Side” Battery or “Middle” Battery in the diagrams below and will cause significant damage to your trolling motor and electronics. The only trolling motor battery that is safe to connect to one of these systems is the “Low Side” Battery.
NOTICE: The internal bonding wire is equipped with a 3 amp fuse. Improper connections described above carrying in excess of 3 amps will blow this fuse and no further damage will be exhibited. If this occurs, RF interference from the trolling motor affecting sonar units and other electronics will be more significant. If the fuse is blown the wiring error should be found and addressed prior to replacing the fuse. The replacement fuse should be 3 amps or less. An intact fuse does not imply correct rigging; significant damage can be done by incorrect wiring without approaching 3 amps of current.
