Detailed description

The Minn Kota MKA-21 quick-release mount in composite is designed to simplify the installation and removal of freshwater trolling motors. It provides a robust and flexible mounting solution for optimized management of your marine equipment. This mount is specifically recommended for Minn Kota Ulterra, Terrova, PowerDrive, PowerDrive V2, and Pontoon PowerDrive motors, as well as for the Deckhand 40.

Modular Design and Adaptive Installation

The MKA-21 consists of an inner plate, an outer plate, a handle assembly, and a locking pin. Its design allows for versatile installation on the boat deck, with the ability to orient the handle and locking pin for inward or outward clearance, adapting to the specific constraints of each vessel. Careful attention must be paid to positioning to ensure sufficient clearance when deploying and stowing the motor.

Compatibility and Limitations of the MKA-21

This mount is compatible with a wide range of Minn Kota freshwater motors. It is essential to note that the MKA-21 must not be used with motors equipped with a 72-inch (183 cm) or longer shaft. Similarly, it is not suitable for 112 lb thrust motors. For saltwater motors (RT range), the RTA-17 mount is the appropriate reference. Assembly and installation are facilitated by the stainless steel fasteners and detailed instructions provided, although assistance is recommended when handling heavier motors.

Expert opinion

« Analysis of the Minn Kota MKA-21 mount: modularity and safety »

The Minn Kota MKA-21 quick-release mount is a strategic accessory for owners of boats equipped with Minn Kota freshwater electric trolling motors. Its composite construction allows for fast attachment and removal of the bow motor, providing significant flexibility for transport, secure storage after use, or to simplify maintenance and cleaning operations. This ability to easily detach the motor helps extend equipment life by protecting it from weather or theft risks when not in use.

This model is specifically designed for Minn Kota Ulterra, Terrova, PowerDrive, PowerDrive V2, and Pontoon PowerDrive freshwater motors, as well as the Deckhand 40. It is essential to note that the MKA-21 is not suitable for motors with a 72-inch or longer shaft or motors with 112 lb thrust. For saltwater applications, the RTA-17 is Minn Kota’s designated alternative.

Installing the MKA-21 requires careful planning of the bow location to ensure sufficient motor clearance in both deployed and stowed positions. It is recommended to position the mount as close as possible to the boat’s centerline to optimize handling and balance. The assembly’s flexibility allows the release handle to be oriented inward or outward, or to port or starboard, to adapt to specific deck constraints and user preferences. For optimal and secure installation, assistance from a second person is strongly advised, particularly due to motor weights that can reach 65 lb.

When securing the mount, especially for Ulterra models, take care to avoid pinching or damaging sensor cables running along the base extrusion. Using the provided stainless-steel hardware, including bolts and nuts, requires slow-speed installation and application of an anti-seize compound to prevent thread galling, ensuring a durable and secure fit. The installation template is printed inside the box, a valuable aid for positioning the drill holes.

What are the important precautions to take when installing the MKA-21 mount?

When installing the MKA-21 mount, several precautions must be taken to ensure safety and proper attachment:

Assistance: It is recommended to have a second person to assist you, as the motor can be heavy and unstable when not secured. Clearance: Before drilling, position the mount and ensure that the motor, once deployed or stowed, does not encounter any obstructions at the bow of your boat. Electrical disconnection: Make sure the motor’s power cables are disconnected from the battery, or that the circuit breaker is in the “off” position. Positioning: Mount the motor as close as possible to the boat’s centerline. Stainless steel bolts: To prevent seizing of stainless steel hardware, do not use high-speed installation tools. Wetting the bolts or applying an anti-seize compound can help. Ulterra installation: If installing on an Ulterra motor, use the clip washers (reference #2201725) provided with your Ulterra motor, not the flat washers included with the MKA-21 mount. Also take care not to pinch the sensor wires along the extrusion base.
