Why Boaters Swear by This Power Port

Anglers and casual boaters alike rave about how the MKR-21 simplifies life on the water. It eliminates the hassle of dangling extension cords or exposed plugs that corrode over time. Instead, you get a professional-grade setup that charges faster and safer. Perfect for overnight trips at the marina or quick top-offs between outings.

Pro Tip for Peak Performance

Position the port near your battery compartment for the shortest cable runs, minimizing voltage drop and maximizing efficiency. Many users mount it low on the transom for easy extension cord access while trailering.

Simple Installation in Minutes

1. Drill a precise hole in your hull using the included template (typically 1-inch diameter).
2. Thread the port through and secure with the locking nut from inside the boat.
3. Apply marine sealant around the exterior flange for an impenetrable seal.
4. Plug in your Minn Kota charger's AC male plug—done!

No electrical expertise required. Most installs take under 15 minutes, leaving you more time on the water.

Perfect Compatibility for Minn Kota Systems

Engineered to work flawlessly with all Minn Kota chargers featuring a standard male AC plug. Whether you're powering up a Terrova, Ulterra, or Quest series trolling motor, this port ensures a secure fit. It's a must-have accessory for anyone serious about maintaining freshwater setups without compromising on quality.

Care and Maintenance for Lasting Durability

Keep it performing like new with these easy habits:

• Rinse with fresh water after every saltwater exposure (though optimized for freshwater).
• Inspect the gasket annually and replace if worn.
• Store the cover snapped shut when not charging.
• Avoid overtightening during install to prevent cracking.

With proper care, it delivers years of trouble-free service, matching Minn Kota's reputation for rugged reliability.
