Minn Kota MKP-38 Weedless Wedge 2 Prop for Trolling Motors - Weed

In this review the Minn Kota MKP-38 Weedless Wedge 2 Prop is evaluated for anglers and boat owners who need a reliable replacement prop that slices through weeds without draining battery life. The bottom line: this prop is for people running trolling motors with a 4-1/2' lower unit diameter who want a durable, easy-to-install OEM-style replacement that includes the nut, pin, and washer. Its patented swept-back, flared-blade design is the primary reason to buy, as it consistently wedges vegetation aside and helps conserve battery power at a range of speeds.

Key Features

• Weedless design: The swept-back, flared-blade profile wedges weeds away to keep the prop turning in cover instead of stalling in vegetation.
• Battery conservation: The shape reduces drag so motors use less power at both low and high speeds, extending run time on a single charge.
• Direct fit: Made to fit 4-1/2' lower unit diameters, so it installs cleanly on compatible Minn Kota trolling motors.
• Complete hardware: The prop ships with a prop pin, nut, and washer so users have what they need to replace the prop right away.
• Drive compatibility: Designed for use with a 1' x 3/16' prop/drive pin and a 3/8'-24 prop nut thread for secure attachment.

Who It's For

This prop is aimed at anglers and small boat operators who frequently run in weedy waters and need a replacement that behaves like factory equipment. It is especially useful for owners of Minn Kota-style lower units around 4-1/2' in diameter and for those who value keeping battery draw low while punching through vegetation.

It is not for users with larger or nonstandard lower units or prop shafts that use different pin sizes or threads; those boaters should verify shaft diameter and thread before ordering. Also, those seeking high-speed performance props for open-water trolling may prefer a different blade profile built for thrust over weed management.

Pros & Cons

• Includes prop pin, nut, and washer so installation is straightforward and complete.
• Conserves battery life by reducing drag compared with standard blades.

Cons

• Some users report mixed vibration levels on certain motors, so a small amount of shaft vibration may occur in specific setups.
• Fits only 4-1/2' lower unit diameters and requires the specified pin and nut sizes, limiting cross-compatibility.
