Minn Kota MKP-9 Prop & Nut Kit A - ⅜"

Keep your Minn Kota trolling motor running smoothly on every outing with the reliable MKP-9 Prop & Nut Kit A. Designed for 3/8-inch props, this essential replacement set ensures you're never sidelined by a worn or damaged propeller nut. Anglers know how props take a beating from underwater obstacles, weeds, and constant use—having a spare kit on hand means quick fixes right on the water or at the dock, minimizing downtime and maximizing your time fishing.

Why This Prop Nut Kit Stands Out for Trolling Motor Owners

Unlike generic hardware store parts, the MKP-9 is precision-engineered by Minn Kota to match the exact tolerances of their popular propellers. The included nut and washer are built tough, typically from corrosion-resistant materials that hold up against freshwater and saltwater exposure. This kit shines in high-weed areas or rocky shallows where props frequently need swapping. It's not just a replacement—it's a safeguard for consistent thrust, quieter operation, and better battery life, as a loose or stripped nut can cause vibrations that sap performance.

• Effortless Maintenance: Swap props in under five minutes with basic tools.
• Peace of Mind: Perfect fit prevents slippage, ensuring full power transfer from motor to prop.
• Versatile for Various Conditions: Ideal for bass boats, kayaks, or pontoons running Minn Kota motors.

Full Compatibility Breakdown

This 3/8-inch kit pairs seamlessly with several Minn Kota propeller models, making it a go-to for owners of mid-range to high-thrust trolling motors. Here's what it fits:

• MKP-2 and MKP-3 Vanishing Props: These innovative designs shear off on impact to protect your motor shaft, and this kit gets you back up fast.
• MKP-6 and MKP-7 Weedless Wedge Props: Built for thick vegetation, where prop damage is common—quick nut replacement keeps you weed-free.
• MKP-25 and MKP-37 Power Props: High-performance options for stronger push in current or wind; reliable hardware maintains peak efficiency.

Pro tip: Always check your prop's shaft size before ordering. If you're unsure, measure the threaded portion—3/8-inch is standard for many 40-80 lb thrust models.

Simple Installation Steps for DIY Anglers

No need for specialized tools or a service center. Grab an adjustable crescent wrench (7/16-inch works best), and follow these steps:

1. Power off and lift the motor out of water for safety.
2. Remove the old nut and washer by turning counterclockwise.
3. Slide on the new washer, then thread the nut clockwise until snug—hand-tighten first, then a quarter-turn with the wrench.
4. Test spin the prop by hand to ensure it spins freely without wobble.
5. Lower back into water and run a quick throttle test.

Regular checks every few trips prevent issues. Tighten seasonally, especially after heavy use in murky waters.

Long-Term Care Tips to Extend Prop Life

To get the most from your MKP-9 kit and props:

• Rinse with freshwater after saltwater trips to combat corrosion.
• Inspect for dings or bends after striking logs—replace promptly to avoid motor strain.
• Pair with anti-seize compound on threads for easier future removals.
• Store motors vertically to reduce prop stress during trailering.

Many anglers keep multiples of this kit in their tackle box—it's lightweight, compact, and a smart investment for uninterrupted adventures.

Equip yourself with the MKP-9 Prop & Nut Kit A and fish with confidence—because every second counts on the water.
