Minn Kota | Trolling Motor Propeller | Weedless Wedge Prop | MKP-7 | 1865006

Product Overview

The Minn Kota | Trolling Motor Propeller | Weedless Wedge Prop | MKP-7 | 1865006 is an authentic original equipment manufacturer (OEM) replacement propeller custom-engineered to deliver elite weed-evasion performance and maximized thrust efficiency for select mid-range Minn Kota trolling motors. When tracking through dense fields of freshwater hydrilla, thick lily pads, milfoil, or heavy brackish marsh grass, standard marine propellers quickly become choked, wrapping strands tightly around the drive shaft hub. This accumulation introduces destructive underwater drag, bogs down the electric motor armature, and rapidly drains your deep-cycle marine batteries. The Minn Kota MKP-7 solves this major environmental obstacle completely by implementing a patented, swept-back blade geometry. This specialized structural design relies on natural centrifugal force to continuously throw weeds and structural vegetation away from the center hub, allowing your boat to glide smoothly through heavy cover at any speed tracking line without stalling out the electrical circuit.

Molded entirely from Minn Kota’s proprietary glass-reinforced composite polymer matrix, this premium 2-blade propeller features an exceptional strength-to-weight ratio. The material is chemically balanced to remain perfectly rigid under full-throttle acceleration, eliminating structural blade flex to translate every ounce of rotational battery energy straight into forward or reverse movement. Precision-balanced from the factory, the MKP-7 fully eliminates lower-unit wobbling and harmonic vibration hums, protecting your internal rubber grease seals from premature wear while preserving absolute silent stealth when sneaking up on wary gamefish over shallow structures. The comprehensive maintenance package arrives fully loaded from the factory and is completely ready for a rapid prop overhaul in the garage or at the boat ramp, containing the standalone premium black composite propeller, an authentic steel shear pin, a heavy-duty brass prop nut, and a flat spacing washer.

Key Features

• Classic Swept-Back Weedless Geometry: Built with unique curved blade edges custom-angled to cleanly shed thick hydrilla, lily pads, and heavy freshwater vegetation without wrapping or clogging.
• High-Tensile Composite Material Matrix: Molded from an advanced, high-density polymer matrix that resists impact chipping, structural warping under heavy load, and UV weathering.
• Maximizes On-Water Battery Lifespan: Precision-balanced architecture completely eliminates lower-unit wobbling and mechanical drag, drastically reducing amp draw to extend runtime.
• 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.
• Restores Silent Steering Performance: Eliminates vibration hums and shaft play along the lower torpedo housing, preserving your stealth presentation in shallow water bays.
• Authentic OEM Part Matching: Certified as an original Minn Kota factory accessory, guaranteeing an absolute, perfect physical seat onto your trolling motor's 3-5/8 inch diameter hub.
• 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-7 (part number 1865006 / factory SKU 1378126) 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 legacy Minn Kota motors utilizing a 3-5/8 inch motor diameter hub.

On the motor side, this kit provides perfect factory matching across specific mid-power Minn Kota lines carrying a **50lb, 55lb, 65lb, or 70lb thrust rating**. This includes legacy generations of the **Minn Kota Maxxum, Forterx, Edge, Terrova, and PowerDrive** bow and transom families. It is critical to note that the MKP-7 **will not fit** newer generation motors that utilize the redesigned Weedless Wedge 2 shape (like the MKP-32), nor will it fit small 30lb to 45lb motors (3-1/4 inch hub) or massive 112lb thrust systems (4-inch hub). Always verify your specific motor's hub diameter and exact factory propeller part number before completing an e-commerce order. It is fully rated for use in both freshwater and saltwater motor lines.

Frequently Asked Questions

What is the primary operational difference between this classic Weedless Wedge and the newer Weedless Wedge 2 props?

The difference comes down to the structural blade profile and matching motor generations. The classic Weedless Wedge MKP-7 features a balanced, curved swept-back edge designed explicitly for older legacy motor lower units built up through the mid-2000s. The newer Weedless Wedge 2 models (like the MKP-32 and MKP-33) utilize an aggressively flared leading edge with swept-back tip points optimized for modern digital variable-speed motors. While both share the core philosophy of shedding grass using centrifugal forces, they cannot be interchanged unless your motor's armature shaft and center hub dimensions match the prop's internal throat perfectly.

How tightly should I screw down the brass prop nut when installing the MKP-7?

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-7 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 50lb and 70lb with a 3-5/8 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.
