E-cowlboy MKR-27 60A Circuit Breaker & MKR-28 Trolling Motor Plug Combo — Waterproof, Ignition‑Protected

The E-cowlboy MKR-27 (60A) circuit breaker paired with the MKR-28 trolling motor plug and receptacle is a waterproof, ignition-protected electrical protection and connection kit designed to fit Minn Kota motors from 12V to 48V.

This two-piece marine electrical kit combines a manual-reset 60 amp circuit breaker (model 1865115) with a sealed plug and receptacle assembly (model 1865120) to offer a compact, service-friendly solution for trolling motor installations. Built from marine-grade materials and rated to handle 1–10 AWG wire and continuous currents up to 60A, the set is intended for freshwater and saltwater use and replaces several older Minn Kota-compatible part numbers.

How does the MKR-27 circuit breaker protect my trolling motor and boat wiring?

The MKR-27 is a manual-reset, 60A breaker engineered to interrupt heavy currents safely and be reset without swapping fuses. Its IP67 waterproof rating and ignition protection reduce the risk of water intrusion and electrical sparks at the breaker location.

• 60 amp current rating suitable for many Minn Kota motor setups (12–48V).
• Stainless steel 1/4" studs resist corrosion in marine environments.
• Push-to-trip button allows quick manual testing and shutdown.
• Protective insulator reduces accidental shorts and improves safety.

What features make the MKR-28 plug and receptacle reliable on the water?

The MKR-28 plug/receptacle uses marine-grade construction and silver-plated terminals for stable conductivity and corrosion resistance. Its fully sealed design with a threaded cap prevents moisture entry while offering flexible mounting and wiring options.

• Accepts 1–10 AWG wire for a wide range of installations.
• Continuous current handling up to 60 amps and up to 48 volts.
• Threaded waterproof cap and dual-mount options for secure installation.
• Includes mounting hardware and splicing-ready connections.

Will this combo replace older Minn Kota connector and breaker models?

Yes — the MKR-28 is designed as a direct upgrade for several previous part numbers, simplifying replacements and retrofit projects. The MKR-27 breaker is likewise compatible with typical trolling motor breaker locations and wiring practices.

• MKR-28 replaces older part numbers like 1865102, 1865124–1865129 and MKR-18/MKR-24–MKR-26 series.
• Fits Minn Kota motors and standard marine wiring arrangements across 12/24/36/48V systems.
• Spare-friendly design eases field swaps without special tools.

How easy is installation and routine use on a boat?

Both components are built for straightforward installation and low-maintenance operation: the breaker mounts with its studs and insulator while the plug assembly mounts with included hardware. The push-to-trip and manual reset on the breaker make testing and resets simple for operators.

• Plug kit includes mounting hardware and adjustable orientation options.
• Breaker uses standard 1/4" stainless studs for common marine terminals.
• Threaded cap keeps the receptacle sealed when not in use.
• Silver-plated terminals and corrosion-resistant materials reduce upkeep.

Who is this for: Boaters, anglers, and marine technicians who need a dependable, upgradeable connection and protection package for Minn Kota trolling motors and similar 12–48V marine electrical systems. It suits users replacing older Minn Kota connectors or adding a compact protective breaker and a sealed power inlet for freshwater or saltwater craft.
