Minn Kota MKP-33 Weedless Wedge 2 Prop Replacement - Fits 4in Motors

In this review the Minn Kota MKP-33 Weedless Wedge 2 prop replacement is evaluated for anglers and boaters who need a reliable spare or upgrade for 4in lower units. The bottom line: this kit is for owners of Ulterra, Riptide, Maxxum, PowerDrive V2, Terrova and compatible motors who want an easy, durable swap to reduce weed and debris entanglement. The reviewer found the part matched OEM fitment, arrived with all installation pieces, and restored quiet, confidence-inspiring thrust in shallow, weed-prone water.

Key Features

• Direct replacement compatibility: Designed as a direct fit for the MKP-33 / part 1865018 so it installs without modification on 4in motor diameters.
• Broad Minn Kota model fit: Works across Ulterra, Riptide, Maxxum, PowerDrive V2 and Terrova series, covering common 80-202lb thrust motor models.
• Complete installation kit: Ships with a large shear pin, support nut, washer and socket wrench so the prop can be installed in minutes.
• Weedless wedge design: Profile reduces weed and debris wrap for smoother operation in shallow lakes and rivers.
• Durable construction: Made from premium materials intended to extend service life and lower replacement frequency.

Who It's For

This prop is ideal for anglers who own Minn Kota-style motors with a 4in lower unit and serial prefixes noted for compatibility, and who fish in areas where weeds or shallow obstacles are common. It is also a good choice for boat owners who prefer carrying a full replacement kit with nut, washer and shear pin for quick field swaps.

It is less suitable for owners of motors with non-4in lower units or those who require specialized high-speed racing props; check your motor diameter and serial prefix before purchase to ensure fitment.
