Minn Kota | Trolling Motor Prop Kit | Prop and Nut Kit D | Trolling Motor Prop Kit | MKP-23 | 1865014

Product Overview

The Minn Kota | Trolling Motor Prop Kit | Prop and Nut Kit D | Trolling Motor Prop Kit | MKP-23 | 1865014 is a professional-grade, maximum-strength marine hardware package engineered to provide a complete structural fastening overhaul for Minn Kota's highest-thrust 36-volt trolling motors. Operating a massive 112-pound thrust motor generates extreme rotational torque, immense hydrostatic pressure, and high structural vibrations, especially when pushing large tournament bass boats, heavy deep-V walleye hulls, or coastal bay boats through rolling open-water waves. Under these punishing conditions, or during sudden high-speed impacts with submerged rock piles and heavy timber, the original factory propeller fasteners undergo severe mechanical fatigue. A bent shear pin or stripped retaining nut can quickly throw your high-power lower unit out of balance, resulting in noisy vibrations that accelerate wear on your rubber oil seals and scare away fish. The MKP-23 kit resolves these critical drivetrain issues completely.

Forged strictly to authentic original equipment manufacturer (OEM) specifications, this heavy-duty Kit D package features high-tensile components precision-machined to provide an absolute, flush compression lock across the propeller hub. Every component is crafted from high-purity, marine-grade stainless steel and non-ferrous brass alloys, ensuring total resistance against salt pitting, rust, and galvanic oxidation in both freshwater environments and high-salinity coastal bays. The comprehensive Prop and Nut Kit D arrives fully loaded from the factory and completely ready for an immediate drop-in hardware refresh, containing an extra-thick steel shear pin, a heavy-gauge nylon-locking nuts, and a large flat backing washer. Keeping a spare kit inside your boat's dry storage box provides essential insurance against on-water breakdowns, letting you execute rapid field repairs and maintain full digital anchoring control when tracking trophy gamefish.

Key Features

• Maximum-Strength Kit D Overhaul: Precision-engineered specifically to safely anchor and lock heavy-duty propellers onto Minn Kota's highest-output 36V 112lb thrust motor drivetrains.
• Nylon-Locking Retention Fasteners: Outfitted with a premium, heavy-gauge nylon-locking nut that creates a permanent mechanical friction lock, preventing the hardware from backing out due to high-vibration running.
• High-Tensile Reinforced Shear Pin: Includes a premium steel shear pin designed to act as a mechanical safety fuse, snapping intentionally during a severe collision to protect the internal motor armature from warping.
• Oversized Flat Spacing Washer: Ships with a marine-grade flat spacing washer that distributes retention clamping pressure evenly across the composite propeller hub to prevent structural cracking.
• Eliminates High-Thrust Vibration: Restores factory-spec tight clamping tolerances along the shaft axis, eliminating lower-unit vibration and wobbling to preserve silent fishing stealth.
• 100% Saltwater and Freshwater 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 MKP-23 Prop and Nut Kit D features a specialized, heavy-duty compatibility profile tailored for elite power systems. It is custom-machined to fit exclusively on Minn Kota 36-volt trolling motor models carrying a 112-pound thrust rating. This primarily encompasses the high-efficiency **Weedless Wedge 2 (MKP-38)** propeller series models.

On the motor side, this hardware kit provides an absolute factory match across Minn Kota's premier 112lb high-thrust lines, including the **Minn Kota Ultrex 112, Ulterra 112, Terrova 112, Fortrex 112, and Riptide 112** freshwater and saltwater bow-mount families. It is critical to note that the MKP-23 **is completely incompatible** with smaller 12V or 24V trolling motor systems pulling 30lb to 80lb of thrust, which utilize smaller shaft diameters and require alternative hardware kits (such as Kit A or Kit B). Always verify your specific motor's thrust rating and shaft profile before completing an e-commerce order.

Frequently Asked Questions

What makes this Kit D hardware setup different from standard Kit A or Kit B prop kits?

The fundamental difference lies in the structural thickness, dimensions, and the specific retention fastener style used to handle extreme power. While smaller kits utilize standard solid brass hex nuts, the MKP-23 Kit D features an advanced nylon-locking nut designed explicitly to counter the intense rotational forces and heavy harmonic vibrations generated by a massive 36V 112lb thrust lower unit. Additionally, the shear pin included in Kit D features a thicker diameter and higher tensile rating to withstand the explosive hole-shot acceleration of tournament bass boats without snapping prematurely.

How tightly should I torque down the nylon-locking nut during installation?

When fastening the premium nylon-locking nut onto your 112lb motor shaft, use a standard 1/2-inch socket wrench or a specialized Minn Kota prop wrench. Tighten the nut clockwise firmly until the internal nylon locking ring engages the steel shaft threads and the flat washer presses completely flush against the composite propeller hub. Give it an additional 1/4 to 1/2 turn to secure the compression lock. Avoid over-tightening with high-powered automatic impact guns, as excessive force can strip the threads, bend the internal shear pin, or crack the prop hub.

Can I safely reuse my old shear pin and lock nut when installing a new propeller?

While it can be tempting to reuse old hardware, Minn Kota strongly recommends installing a fresh, matching hardware kit like the MKP-23 whenever you replace your propeller. Over multiple seasons of high-thrust operation, the original shear pin can develop microscopic stress fractures from minor underwater impacts, and the internal nylon ring of the lock nut gradually loses its frictional retention capability after being removed and reinstalled. Using a fresh kit ensures your propeller remains perfectly centered and locked tightly to prevent accidental backing out while running on plane.

Is this black Kit D hardware safe to use on white Riptide 112lb saltwater trolling motors?

Yes, absolutely. The Minn Kota MKP-23 Prop and Nut Kit D is fully certified and compatible with all white Minn Kota Riptide saltwater bow-mount trolling motor models carrying a 112-pound thrust rating. The marine stainless steel and high-purity non-ferrous alloys used to forge these fasteners are completely immune to salt air pitting, rust, and galvanic corrosion. They deliver the exact same heavy-duty holding power on high-salinity coastal bays and tidal flats as they do on freshwater lakes, keeping your drivetrain working perfectly.

What is the proper method for clearing a tangled fishing line from behind my 112lb prop hub?

Clearing line tangles is an essential routine maintenance step that should be performed multiple times each season. First, ensure your trolling motor is fully powered off and isolated from the battery grid. Use a wrench to unscrew the nylon-locking nut from the MKP-23 kit, slide off the flat washer, and pull the propeller straight off the shaft. Use a pair of needle-nose pliers or a sharp utility knife to carefully cut and extract any wrapped loops of monofilament or braided line bundled around the shaft sleeve. This simple process protects your rubber oil seals from tearing, preventing catastrophic lower-unit water intrusion.
