Sxkxm MKP-38 Weedless Wedge Replacement Prop for Minn Kota 4-1/2" Lower Units — Flared Weed-Shedding Blades, Includes Drive Pin

The Sxkxm MKP-38 Weedless Wedge 2 is a replacement trolling motor prop designed to shed weeds, preserve battery life, and fit select Minn Kota lower units.

Replace a worn or clogged propeller with the MKP-38 to keep your trolling motor running smoothly in shallow, vegetation-rich water. Built for easy installation and reliable performance, this prop uses swept-back, flared blades to deflect weeds while maintaining thrust at low speeds. It’s molded from durable plastic to resist damage from debris and saltwater exposure, and ships with the correct drive pin and prop nut thread for a direct fit on compatible Minn Kota models.

Which Minn Kota models will this prop fit?

The MKP-38 is engineered as a direct replacement for a range of 1 HP and 112 series Minn Kota motors that use the MKP-38 specification. It matches the 4-1/2" lower unit diameter and the prop nut thread standard for these units.

• Compatible with models bearing serial prefixes O through V
• Fits EO 1 HP, Fortrex 112, Terrova 112 and similar 112-series motors
• Also fits riptide and Ultrex/Ulterra variants listed in product details
• Includes 1" x 3/16" drive pin and 3/8"-24 prop nut thread

How does the weedless wedge design help when fishing in heavy vegetation?

Blade geometry is key: the swept-back, flared design redirects weeds away from the blade path so the prop keeps pushing without bogging down. That reduces sudden motor stalls and the extra battery draw that comes from trying to power through entangled plants.

• Flared blades shed weeds rather than trapping them
• Maintains propulsion at slow troll speeds for stealthy approaches
• Helps extend run time by avoiding high-current stalls
• Balanced shape for consistent, vibration-free rotation

What are the build and installation details I should know?

The prop is molded from high-quality marine-grade plastic to resist cracking and corrosion while remaining light enough for smooth spin. Installation is straightforward: fit the supplied drive pin, slide the prop on the 4-1/2" lower unit shaft, and secure with the 3/8"-24 nut.

• Material: reinforced plastic suitable for freshwater and saltwater use
• Dimensions: fits 4-1/2" lower unit diameter
• Hardware: 1" x 3/16" prop/drive pin included
• Thread spec: prop nut thread 3/8"-24 for direct replacement

Will this prop handle rough underwater encounters and debris?

While designed to resist entanglement and reduce snagging, the MKP-38 is a plastic prop, so it prioritizes flexibility and impact resistance over the toughness of metal. It tolerates common underwater obstacles and is easier to replace if damaged compared with more rigid alternatives.

• Plastic construction tolerates knocks and scrapes without immediate failure
• Weed-shedding profile limits time spent clearing clogs
• Suitable for environments with weeds, lily pads, and light debris
• Economical to replace if severely damaged

Who is this for? The Sxkxm MKP-38 is aimed at anglers and boaters who use Minn Kota 1 HP and 112-series trolling motors in shallow or vegetated waters and need a reliable, weed-shedding spare prop. It’s a practical upgrade for fishermen who want fewer interruptions from weeds, simpler on-water maintenance, and the confidence of a direct-fit replacement that includes the correct drive pin and nut specifications.
