Minn Kota MKP-40 Power Prop 4-1/2" Quest Series Propeller - One Size, High-Thrust Durable Design

Minn Kota MKP-40 Power Prop is a 4-1/2" propeller engineered for QUEST Series trolling motors to deliver improved thrust, torque, and durability in a compact, drop-in design. The MKP-40 Power Prop was created specifically for Minn Kota QUEST Series lower units to help anglers push through weeds, chop, and heavy cover while maintaining efficient speed and control. This propeller ships with the prop pin, nut, and washer needed for installation, and its blade profile is tuned to balance power delivery with battery efficiency so your motor remains responsive without unnecessary draw.

How does this propeller improve performance on the water?

The MKP-40 is shaped to convert motor RPM into forward thrust more effectively, giving better acceleration and steadier top-end control. Its profile increases torque for punch through vegetation and improves tracking when you need precise boat positioning.

• Optimized blade geometry for stronger thrust and improved hole-shot.
• Designed to reduce cavitation and maintain prop bite in shallow cover.
• Tuned for QUEST Series power curves to balance speed and endurance.

Will the MKP-40 fit my trolling motor and how easy is installation?

This propeller is made exclusively for 4-1/2" QUEST Series lower units and matches the factory blade clearance and hub dimensions. Installation is straightforward: slide the prop onto the shaft and secure it with the included prop pin, nut, and washer—no extra hardware required.

• Fits 4-1/2" QUEST Series lower units only for a precise fit.
• Includes prop pin, nut, and washer for complete installation.
• No special tools or extra parts typically needed for swap-out.

What materials and construction ensure durability?

The MKP-40 is built from heavy-duty materials chosen to withstand repeated impacts and the abrasive demands of fishing environments. Its reinforced hub and blades resist deformation, keeping performance consistent after heavy use.

• Robust construction tolerates rocks, weeds, and frequent launches.
• Blade stiffness maintains thrust and reduces flex-related inefficiencies.
• Corrosion-resistant finish extends service life in freshwater and light brackish conditions.

How does this prop affect battery life and motor efficiency?

The MKP-40’s design aims to match the QUEST motor’s torque curve so the motor works efficiently across common throttle ranges. By delivering power where the motor needs it, you can expect better responsiveness without excessive current draw in typical fishing scenarios.

• Tuned for efficient power transfer to preserve battery runtime.
• Improved bite reduces time spent fighting resistance, saving energy.
• Smooth blade engagement lowers surges that can spike current draw.

Who is this for? The Minn Kota MKP-40 Power Prop is suited for anglers and boaters who own a 4-1/2" QUEST Series trolling motor and want a ready-to-install prop that improves thrust, handles cover better, and stands up to rugged use. If you fish in weedy lakes, need reliable hole-shot for precise positioning, or just want a durable OEM-matched replacement with complete installation hardware included, this propeller is a practical upgrade.
