Minn Kota | Power Prop | Trolling Motor Propeller | MKP-2 | 1865002

Product Overview

The Minn Kota | Power Prop | Trolling Motor Propeller | MKP-2 | 1865002 is a high-efficiency, tournament-grade marine propulsion component engineered to maximize the raw pushing power, structural acceleration, and battery runtime of your small-to-midsize Minn Kota trolling motor. Operating as an authentic original equipment manufacturer (OEM) part, this 2-blade propeller features an aggressive, high-torque blade geometry designed specifically to move light-to-medium boat hulls through windy shorelines, light river currents, and choppy lake flats. Over multiple seasons of active angling, an original prop can easily become nicked by submerged rocks, scarred by gravel beds, or warped by tightly wrapped lines. These minor cosmetic imperfections create substantial underwater drag and structural imbalances, causing your trolling motor to vibrate loudly, drain your deep-cycle batteries prematurely, and lose critical top-end thrust. The MKP-2 restores your lower unit back to factory-fresh efficiency.

Molded entirely from Minn Kota's proprietary, glass-reinforced composite polymer matrix, the Power Prop features an exceptional strength-to-weight ratio. The material is chemically balanced to remain completely rigid under full-throttle acceleration, eliminating blade flex to translate every ounce of rotational battery energy straight into forward or reverse movement. A major design highlight of the MKP-2 is its sweeping blade profile, which is highly optimized for slicing cleanly through freshwater vegetation, hydrilla, milfoil, and heavy lily pads without wrapping or stalling out the motor. The comprehensive replacement kit arrives fully loaded from the factory and completely ready for a rapid prop swap, containing the standalone black 2-blade propeller, an authentic steel prop pin (shear pin), a heavy-duty brass prop nut, and a premium flat washer.

Key Features

• High-Torque 2-Blade Design: Engineered with a wide, aggressive blade geometry that maximizes raw pushing power and open-water acceleration for small-to-midsize fishing boat configurations.
• Glass-Reinforced Composite Build: Molded from an advanced, high-density polymer matrix that resists impact chipping, structural warping under heavy load, and UV weathering.
• Weed-Slicing Optimization: Swept-back blade edges are custom-angled to cleanly cut through thick hydrilla, lily pads, and heavy freshwater vegetation without wrapping or stalling the motor armature.
• Complete Hardware Kit Included: Arrives fully loaded from the factory with a replacement steel shear pin, a heavy-duty brass prop nut, and a custom flat backing washer for a tool-free hardware refresh.
• Maximizes On-Water Battery Lifespan: Precision-balanced to fully eliminate lower-unit wobbling and excessive mechanical drag, drastically reducing the amp draw on your deep-cycle batteries to extend runtime.
• Authentic OEM Part Matching: Certified as an original Minn Kota manufacturer accessory, guaranteeing an absolute, perfect physical seat onto your trolling motor's armature shaft.

Compatibility Information

The Minn Kota Power Prop MKP-2 (part number 1865002 / factory SKU 1378121) features a highly specific compatibility layout centered around the diameter of your trolling motor's lower unit torpedo housing. It is engineered explicitly to fit Minn Kota motors utilizing a smaller 3-1/4 inch motor diameter hub.

This includes extensive compatibility with specific power brackets across the modern and legacy **Minn Kota Endura, Endura C2, Endura Max, Edge, Traxxis, PowerDrive, and PowerDrive V2** series motors that carry a **30lb, 36lb, 40lb, 45lb, or 50lb thrust rating**. It is critical to note that the MKP-2 **will not fit** mid-range 55lb to 70lb motors (which use a 3-5/8 inch hub, like the MKP-37) and it **is completely incompatible** with heavy-duty 80lb or 112lb motors (which utilize a larger 4-inch hub, like the MKP-33 or MKP-38). Always verify your specific motor's thrust rating and hub diameter before completing a replacement order. It is completely rated for use in both freshwater and saltwater motor lines.

Frequently Asked Questions

What is the purpose of the small steel pin included in the prop kit, and how do I replace it?

The small steel pin is called a shear pin, and it serves as a critical mechanical safety fuse designed to protect your trolling motor's internal armature shaft from catastrophic structural damage. When you are running your motor and the spinning prop violently strikes a solid underwater hazard—such as a large rock, concrete boat ramp, or a heavy submerged log—the shear pin is engineered to snap in half intentionally. This break decouples the prop from the engine, preventing the high-impact shock from bending the main steel drive shaft or shattering the internal magnets. To replace it, simply slide the old broken pieces out of the hole in the shaft, slide the new pin in horizontally, and align the groove on the back of the MKP-2 prop directly over the pin.

How tightly should I screw down the brass prop nut when installing the MKP-2?

When fastening the heavy-duty brass prop nut onto the threaded end of your trolling motor shaft, it is vital to tighten it down securely without crushing the components. Using a standard 1/2-inch wrench or a specialized Minn Kota prop wrench tool, tighten the nut clockwise until it makes firm physical contact with the flat washer and the propeller hub, then give it an additional 1/4 to 1/2 turn to lock it in place. Never use a high-powered electric impact driver to tighten the prop nut, as excessive mechanical torque can easily strip the brass threads, snap the armature tip, or crack the composite plastic hub of your brand new propeller.

What is the performance difference between this 2-blade Power Prop and a 3-blade Weedless Wedge prop?

The choice between a 2-blade Power Prop (MKP-2) and a 3-blade Weedless Wedge prop comes down to your primary operating environments and speed tactics. A 2-blade Power Prop features wider, more aggressive individual blades that capture a larger volume of water, making it superior for achieving maximum top-end speed, accelerating quickly, and pushing heavy boat hulls against strong river currents or high wind drift lines. A 3-blade Weedless Wedge prop focuses its geometry on extreme weed evasion, using swept-back curved blades to push away thick vegetation without wrapping, but it sacrifices a slight amount of raw top-end forward thrust to achieve that stealth.

Why is my trolling motor vibrating loudly after installing this new replacement prop?

If your trolling motor exhibits a loud humming noise or heavy physical vibration after installing the MKP-2, it is typically caused by one of two installation alignment issues. First, check to ensure that the internal steel shear pin is sitting perfectly centered inside its shaft slot and has not slid slightly to one side, which will cause the propeller to seat crookedly. Second, inspect the prop shaft itself for any tangled loops of braided fishing line wrapped behind the prop. A buildup of compressed fishing line can push the prop forward out of balance and can quickly destroy the lower unit's rubber oil seals, allowing water to leak into the electric motor compartment.

Can I safely use this black replacement propeller on a white Minn Kota Riptide saltwater motor?

Yes, absolutely. From a purely structural, mechanical, and physical standpoint, the MKP-2 Power Prop is fully compatible with white Minn Kota Riptide saltwater trolling motor models, provided the Riptide motor carries a matching thrust rating between 30lb and 50lb with a 3-1/4 inch hub diameter. Minn Kota’s composite props are completely inert and non-metallic, meaning they contain no components that can rust, pit, or suffer from galvanic corrosion in high-salinity coastal bays. The only difference is cosmetic—installing this black prop onto a white Riptide lower unit will create a black-and-white contrast layout, but it will deliver the exact same high-thrust performance on the water.
