Minn Kota | Trolling Motor Propeller | Weedless Wedge Prop | MKP-6 | 1865003

Product Overview

The Minn Kota | Trolling Motor Propeller | Weedless Wedge Prop | MKP-6 | 1865003 is a highly reliable, factory-certified replacement propeller engineered to provide dependable weedless efficiency and consistent pushing power for small-to-midsize Minn Kota trolling motors. Operating a small fishing watercraft, jon boat, or backcountry skiff inside thick fields of lily pads, pond weeds, and heavy hydrilla can quickly choke standard propellers, wrapping the vegetation tightly around the drive shaft and stalling out your electric motor. The Minn Kota MKP-6 addresses this operational obstacle by incorporating a classic, swept-back blade profile. This specialized geometric architecture forces loose weeds and thick marsh grass to continuously slide outward away from the hub faceplate, letting your vessel glide smoothly through choked flats at any speed tracking line without forcing you to constantly clear the lower unit by hand.

Molded entirely from Minn Kota's proprietary glass-reinforced composite polymer matrix, the Weedless Wedge features an exceptional strength-to-weight ratio. The material is chemically balanced to remain completely rigid under full-throttle acceleration, eliminating structural blade flex to translate your battery's electrical energy straight into clean forward or reverse thrust. Precision-balanced from the factory, the MKP-6 fully eliminates lower-unit wobbling and harmonic vibration hums, protecting your internal grease seals while lowering amp draw to maximize your battery runtime on long fishing days. The comprehensive replacement kit arrives fully loaded from the factory and is ready for a rapid prop swap, containing the standalone black 2-blade propeller, an authentic steel shear pin, a heavy-duty brass prop nut, and a flat washer.

Key Features

• Classic Swept-Back Weedless Geometry: Outfitted with swept-back, curved blade edges custom-angled to cleanly shed thick hydrilla, lily pads, and heavy freshwater vegetation without wrapping.
• High-Tensile Composite Build: Molded from an advanced, high-density polymer matrix that resists impact chipping, structural warping under heavy load, and UV weathering.
• Complete Installation Hardware Pack: 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 equipment manufacturer replacement accessory, guaranteeing an absolute, perfect physical seat onto your trolling motor's armature shaft.
• Freshwater and Saltwater Approved: Forged from high-purity non-ferrous alloys that are completely immune to salt rust, pitting, and oxidation from brackish water exposure.

Compatibility Information

The Minn Kota Weedless Wedge Prop MKP-6 (part number 1865003 / factory SKU 1378122) 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, and older PowerDrive** bow and transom families carrying a **30lb, 35lb, 40lb, 45lb, 50lb, or 55lb thrust rating** operating on a single 12V battery circuit. It is critical to note that the MKP-6 **will not fit** large heavy-duty motors carrying an 80lb or 112lb thrust rating, which utilize thicker 1/2-inch drive shafts and larger hubs (like the MKP-33 or MKP-38). Always verify your specific motor's shaft diameter and thrust rating before ordering.

Frequently Asked Questions

What is the difference between this classic Weedless Wedge MKP-6 prop and the newer Weedless Wedge 2 models?

The difference comes down to the hub housing size and the specific generation of blade engineering. The classic Weedless Wedge MKP-6 is scaled explicitly for smaller, lighter 3-1/4 inch motor hubs typical of 12V motors under 55 pounds of thrust. The newer Weedless Wedge 2 models (like the MKP-32 or MKP-33) are built with an extra-wide, aggressively flared blade profile tailored specifically for larger 3-5/8 inch and 4-inch high-thrust 24V and 36V motor lower units. Both models utilize the same swept-back design principles, but they cannot be interchanged due to the different hub diameters.

How tightly should I screw down the brass prop nut when installing the MKP-6?

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 propeller.

What is the purpose of the small steel pin included in this prop kit?

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 electric motor from catastrophic structural damage. When you are tracking along a shallow flat or weedy marsh bank and the spinning propeller violently strikes a solid underwater hazard—such as a large rock, concrete boat ramp, or heavy submerged log—the shear pin is engineered to snap in half intentionally. This mechanical break decouples the prop from the engine, preventing the high-impact shock from bending the main steel armature shaft or shattering the internal magnets, allowing you to easily replace the pin rather than the entire motor.

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-6 Weedless Wedge 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 55lb 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.

What should I look for behind the propeller when replacing this hardware kit?

Whenever you slide your propeller off the shaft to replace the shear pin or prop nut, you should always take 30 seconds to closely inspect the exposed metal shaft and the rubber grease seal behind it. Look for any tangled loops of braided or monofilament fishing line wrapped tightly around the shaft. Spinning propellers can easily suck in loose fishing lines left floating in the water. If left uncleaned, this line will become compressed by the prop hub, heat up, and cut directly through the lower unit's rubber oil seals, allowing water to leak into the electric motor compartment and cause catastrophic internal electrical failure.
