MKP-33 Trolling Motor Prop Weedless Wedge 2 - Fits 4in Lower Units

In this review of the MKP-33 trolling motor propeller the bottom line is simple: this is a practical, low-cost replacement for anglers who need a reliable weed-shedding prop for Minn Kota style motors. The reviewer found the MKP-33 to be particularly useful for running through heavy vegetation at slow speeds because the swept-back, flared blade shape wedges weeds away while conserving battery power. Installation is straightforward and the kit includes the prop drive pin and prop nut with a 3/8-24 thread, so it is ready to fit 4in lower unit diameters for many common models.

Key Features

• Wide model compatibility: Fits a long list of Minn Kota style motors including PowerDrive, Riptide, Terrova, Ulterra and Ultrex families for broad replacement use.
• Weedless Wedge 2 design: Swept-back and flared blades help deflect weeds and allow steady propulsion through vegetation without overloading the motor.
• Included hardware: Ships with a 1in x 3/16in prop drive pin and a prop nut with 3/8-24 thread so users do not need to source extra parts.
• Fits 4in lower unit diameter: Designed specifically for lower units with a 4in diameter to ensure a secure fit on compatible shafts.
• Durable plastic construction: Molded from marine-grade plastic intended to resist corrosion and withstand typical boating impacts and debris contact.

Who It's For

This propeller is best for freshwater anglers who run Minn Kota style trolling motors and who frequently encounter weeds or shallow water cover; it is built to wedge vegetation away and keep you moving at trolling speeds. It also fits owners of a wide range of models who want a quick replacement without complicated parts hunting.

Less suitable are users who need a metal prop for extreme durability against rocks or saltwater corrosion, and those with lower unit diameters other than 4in should look for a size-matched propeller instead.

Pros & Cons

Pros

• Effective weed-shedding blade shape helps maintain forward thrust in vegetation.
• Broad compatibility with many Minn Kota style models simplifies replacement decisions.
• Comes with prop pin and nut so installation is fast and complete.

Cons
