Minn Kota MKR-21 AC Power Port - Freshwater

The Minn Kota MKR-21 AC Power Port for Freshwater is a thru-hull connection adapter that eliminates the need to cut or splice extension cords when connecting AC power to your trolling motor charger. Designed for anglers who demand quick, reliable shore power connections without permanent modifications to the boat's electrical infrastructure, this adapter accepts the male AC plug from any Minn Kota charger and delivers watertight connectivity in freshwater environments.

The integrated watertight cover and gasket system protect the AC connection from corrosion and moisture intrusion when the charger is disconnected, a critical feature for boats stored in damp conditions or left at the dock between trips. This passive protection extends the life of both the port and the charger plug by preventing oxidation and salt spray damage. The compact design (5 x 3 x 7 inches) integrates cleanly into transom or hull-mounted installation without consuming significant deck space, and at 0.2 lbs, it adds negligible weight to the vessel.

Weekend fishermen and serious freshwater anglers benefit equally from this Minn Kota accessory. Those who rotate between multiple boats or travel frequently gain the speed and safety of a permanent shore power connection without having to rewire the vessel. Charter operators and rental fleets find the standardized Minn Kota plug interface streamlines charging logistics across multiple motors. Any boater running a Minn Kota trolling motor charger in freshwater conditions should consider this port an essential protection investment—it solves the practical problem of managing AC power connections while safeguarding expensive electronics from environmental damage.
