Minn Kota MKA-57 Quick Release Bracket: Effortless Security and Convenience for Your Trolling Motor
Item # 1854057
Experience unparalleled convenience and peace of mind with the Minn Kota MKA-57 Quick Release Bracket. Engineered for anglers who demand both robust security and operational flexibility, this heavy-duty bracket allows for the quick and easy removal and reattachment of your trolling motor. This feature is invaluable for storage, security, and trailering, ensuring your investment remains safe and your time on the water is maximized.
A standout feature of the MKA-57 is its innovative sliding mechanism, which allows the motor to be moved 10 inches inboard. This provides crucial clearance for boat covers, preventing snags and wear, and offers additional space when launching or mooring in tight quarters.
Constructed from durable, anodized aluminum with stainless steel components and hardware, the MKA-57 is built to withstand the harshest freshwater and saltwater environments, offering exceptional corrosion resistance. The dual cam-lock design ensures a rock-solid connection to the boat deck, significantly reducing bracket movement and operational noise for a quieter fishing experience. For an added layer of protection, the upper and lower plates feature a slot for a padlock (not included), allowing you to securely lock your motor to the boat.

- Quick Release Functionality: Effortlessly remove and reattach your trolling motor without the need for tools.
- 10-Inch Inboard Slide: Provides additional clearance for boat covers and launching.

Applicable Models:
The Minn Kota MKA-57 Quick Release Bracket is specifically designed to handle the increased stress and torque of high-thrust motors with long shafts. It is compatible with all Minn Kota electric steer trolling motors featuring QUEST Technology, including:
- Ulterra QUEST™ Series (All models)

Substitute Part Numbers:
The Minn Kota MKA-57 (Item # 1854057) is a unique bracket offering both a quick-release function and a 10-inch slide specifically for QUEST series motors. Currently, there are no direct substitute part numbers from Minn Kota that offer this identical combination of features for the same range of compatible motors.
While other quick release brackets are available from Minn Kota, they are intended for different motor series or lack the sliding feature. For example, the MKA-56 and RTA-55 are compatible with QUEST series motors but do not have the inboard slide capability. Therefore, for anglers seeking the specific functionality of the MKA-57, it is the recommended and purpose-built solution. Always ensure you are selecting the correct bracket for your specific trolling motor model to guarantee proper fit and performance.
