Minn Kota MKP-7 Weedless Wedge Prop for Trolling Motors — 3-5/8" Hub, Weed-Resistant Composite

The Minn Kota MKP-7 Weedless Wedge Prop is a 100% weed-resistant replacement propeller that pushes vegetation aside to keep your trolling motor running efficiently.

The MKP-7 Weedless Wedge Prop is built for anglers and boaters who navigate weedy, debris-filled water. Engineered to fit motors with a 3-5/8" diameter, this durable composite prop restores thrust while minimizing fouling, conserving battery power and maintaining steady speed in heavy cover. The prop ships complete with the prop nut, pin, and washer for immediate installation.

How does this propeller reduce weed fouling on my trolling motor?

The wedge-shaped blades are sculpted to deflect and shear aquatic vegetation rather than allow it to wrap around the shaft. That design keeps the blades clear so the motor can maintain torque and avoid stalls that drain the battery.

• 100% weedless geometry that pushes weeds away from the hub
• Blades angled to shed vegetation rather than trap it
• Works at slow trolling speeds where fouling typically occurs

Will the MKP-7 fit my motor and how durable is it?

This prop is sized for motors with a 3-5/8" diameter hub, a common mid-size trolling motor standard. It’s molded from an impact-resistant composite to stand up to submerged obstacles, rocks, and repeated use without cracking or losing shape.

• Compatible with 3-5/8" motor diameter hubs
• Impact-resistant composite material for long service life
• Includes prop nut, pin, and washer for complete replacement

How does using the MKP-7 affect battery life and performance?

By limiting vegetation wrap and maintaining steady thrust, the MKP-7 reduces the motor’s load spikes and frequent stalls that consume extra amps. The result is more efficient energy use and longer run times on a single charge, especially in heavy cover.

• Minimizes current-drawing stalls caused by weeds
• Helps preserve battery power during extended trolling sessions
• Maintains smoother, more consistent thrust at low speeds

What hardware and installation details should I know?

The MKP-7 includes the prop nut, pin, and washer so you won’t need to source extra parts for a standard replacement. Installation follows typical prop removal and refit steps for 3-5/8" hub motors; if uncertain, follow your motor’s manual or have a technician install it.

• Comes with prop nut, retaining pin, and washer
• Simple swap for standard 3-5/8" diameter motors
• Refer to your motor manual for torque and securing instructions

Who is this for: The Minn Kota MKP-7 Weedless Wedge Prop is ideal for anglers, guides, and recreational boaters who regularly run through weeds, lily pads, or debris and need a reliable, plug-and-play prop that preserves battery life and keeps their mid-size trolling motor moving. It’s a good upgrade or replacement for anyone with a 3-5/8" motor hub who wants fewer interruptions and less maintenance in vegetated waters.
