The PalpitateC MKP-38 Weedless Wedge 2 is a 4-1/2" replacement propeller engineered to cut through weeds, reduce entanglement, and restore smooth, quiet performance to compatible Minn Kota trolling motors.

Replace a worn or damaged propeller with this purpose-built MKP-38 Weedless Wedge 2 and get back reliable thrust in shallow or vegetation-heavy water without sacrificing battery life. Crafted from corrosion-resistant plastic and supplied with the prop pin and nut required for installation, this prop is shaped to reduce snags and maintain steady control across popular Minn Kota models with a 4-1/2" motor diameter.

Which Minn Kota motors will this MKP-38 propeller fit?

This prop is sized for Minn Kota 4-1/2" diameter engines and is compatible with many EO 1 HP, Fortrex 112, Terrova 112, Ulterra 112, and Riptide series motors. It replaces OEM part numbers 1378160 and 1865023 and fits motors whose serial number prefixes range from "O" through "V."

• Designed for 4-1/2" diameter Minn Kota models
• Direct replacement for parts 1378160 and 1865023
• Compatible with serial prefixes O–V
• Includes 1" x 3/16" prop/drive pin and 3/8"-24 prop nut

How does the Weedless Wedge 2 design help when fishing in vegetation?

The swept-back, flared blades are shaped to slice through weeds and minimize material wrap, so the motor keeps turning even in heavy cover. This reduces interruptions during trolling or positioning and helps preserve battery life by keeping the prop spinning efficiently.

• Flared blades push weeds away rather than catching them
• Swept-back profile reduces drag and improves flow
• Maintains consistent RPMs for better battery economy

What materials and durability can I expect from this replacement prop?

Manufactured from a high-quality corrosion-resistant plastic, the MKP-38 balances light weight with impact resistance to withstand submerged obstacles and regular use. The material resists rust and electrochemical degradation common in marine environments, making it a practical long-term replacement.

• Corrosion-resistant thermoplastic construction
• Lightweight yet impact-tolerant design
• Resistant to salt and freshwater degradation

Is installation difficult and what hardware is included?

Installation is straightforward and requires no specialized tools: remove the old prop, slide on the MKP-38, secure the included prop/drive pin and prop nut, and you're ready to go. The universal fit and supplied fasteners make it an easy field replacement between fishing trips.

• No special tools required for most installations
• Supplied 1" x 3/16" prop/drive pin and 3/8"-24 prop nut
• Quick swap restores smooth, quiet operation

Who is this for: The PalpitateC MKP-38 Weedless Wedge 2 is for anglers and boaters who use Minn Kota trolling motors in weed-choked or shallow waters and need a durable, easy-to-install propeller that reduces snags and conserves battery life. It’s also a good option for anyone replacing the original 1378160 or 1865023 prop on compatible 4-1/2" Minn Kota models, or for those seeking a corrosion-resistant spare to keep on board.
