3. Setup and Installation

Proper installation is crucial for the performance and longevity of your Minn Kota Ultrex trolling motor. Follow these general guidelines for setup.

3.1 Mounting the Motor

The Ultrex is a bow-mount trolling motor. Securely attach the motor to the bow of your boat using the provided mounting hardware. Ensure the mounting surface is flat and strong enough to support the motor's weight and operational forces. Refer to the detailed mounting template included with your product for precise hole placement.

3.2 Electrical Connection

The Ultrex 112 lb thrust motor operates on a 36-volt system. Connect the motor to three 12-volt deep cycle marine batteries wired in series. Use appropriate gauge wiring and circuit protection as specified in the full installation guide to prevent damage and ensure safety. Ensure all connections are tight and corrosion-free.

3.3 Deploying and Stowing

The patented Lift-Assist Design significantly reduces the effort required to deploy and stow the motor. To deploy, release the motor from its stowed position and gently lower it into the water. To stow, lift the motor using the handle until it locks into the stowed position. The nitrogen gas-charged spring assists in this process.

• Spot-Lock with Jog: Activates an electronic anchor to hold your boat in a precise GPS location. Use the Jog feature (with heading sensor) to move your boat five feet in any direction from the Spot-Lock position.
• AutoPilot: Automatically navigates your boat in a set direction, correcting for wind and current.
• Record Paths: Save and retrace your fishing paths.
• Follow Depth Contours: Navigate along specific depth contours when linked to a Humminbird fish finder.
• Speed and Steering Control: Adjust motor speed and direction directly from the remote.

4.3 Digital Maximizer

The Digital Maximizer technology provides variable speed control, delivering only the necessary power to the motor. This results in up to five times longer run time on a single battery charge compared to fixed-speed motors.

4.4 Built-in MEGA Down Imaging

The motor features a transducer built directly into the lower unit, providing clear Humminbird MEGA Down Imaging sonar views. This integrated design offers a clean, protected look and eliminates external transducer mounting.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your trolling motor.

• After Each Use: Rinse the motor with fresh water, especially after use in saltwater or brackish water. Inspect the propeller for fishing line, weeds, or debris. Remove any obstructions to prevent damage to the prop or motor shaft seal.
• Propeller Inspection: Periodically check the propeller for nicks, cracks, or bends. Replace damaged propellers (MKP-38) to maintain efficiency and prevent vibration.
• Battery Care: Ensure batteries are fully charged before each use. Store batteries in a cool, dry place and keep terminals clean and free of corrosion.
• Shaft and Mount: Inspect the composite shaft for any signs of damage. Check the mounting bolts for tightness and ensure the mount operates smoothly.
• Electrical Connections: Regularly inspect all electrical connections for corrosion or loose wiring. Apply dielectric grease to connections to prevent corrosion.
