MKP-2 Power Prop by Minn Kota
The MKP-2 is designed to deliver extra power to push through vegetation and currents. It fits 3-1/4″ motor diameters and supports motors up to 35 lb thrust. Its rugged, impact-resistant composite construction aims for durability in tough water. Best for anglers who navigate thick weed beds at moderate speeds and want reliable propulsion. Limitation: compatibility is focused on smaller motors; check your lower unit diameter before purchase.
MKP-32 Weedless Wedge 2 Prop
MKP-32 is designed for Minn Kota motors with a 3-5/8″ diameter lower unit, covering a wide set of models from 2005 onward. Its swept-back, flared blades help wedge weeds away while conserving battery power, enabling movement through heavy vegetation even at slower speeds. Choose this if you fish in dense weed areas and require broad compatibility. Caution: verify your motor’s serial prefix to ensure fit.
Newport 3-Blade Trolling Propeller Kit
This Newport propeller kit is built for Newport 55lb, 62lb, and 86lb motors, offering a complete kit: blade, drive pin, nut, washer, and a spanner tool. Made from fiberglass-reinforced nylon, it emphasizes long-term strength and impact resistance. Best for Newport motor users who want a ready-to-install kit. Limitation: designed for specific Newport thrust ranges; ensure your model matches.
MKP-38 Weedless Wedge 2 Prop
MKP-38 is designed for 4-1/2″ lower unit diameters, using a 1″ x 3/16″ drive pin and 3/8″-24 prop nut thread. It focuses on weedless performance while enabling operation at slower trolling speeds. Best for larger lower units and anglers who encounter heavy aquatic growth. Limitation: larger diameter may require careful installation and spacing on some setups.
MKP-33 Weedless Wedge 2 Prop
MKP-33 targets 4″ lower unit diameter with the same swept-back, weed-clearing design as MKP-32. It’s compatible with a broad range of Minn Kota models, making it a versatile option for weed-prone waters. Best for anglers who need a robust weed-cutting prop across several motor configurations. Limitation: ensure your motor’s exact diameter and serial prefix for a perfect fit.
Buying Guide: Key Considerations for Trolling Motor Speed Props
Is your motor compatible? Check the lower unit diameter and drive pin size before selecting a prop. Materials vary; fiberglass-reinforced nylon balances strength and weight for efficiency. Blade design matters: swept-back, flared blades slice through weeds while conserving battery power. Consider the water you fish: heavy vegetation benefits from weedless wedges, while clear water may prioritize speed and thrust.
Which prop is right for you?
- Best for dense vegetation and smaller motors: MKP-2 Power Prop
- Best for broad Minn Kota compatibility and weed-prone waters: MKP-32 or MKP-33
- Best for Newport motors: Newport 3-Blade Kit
- Best for larger lower units and weed clearance at slow speeds: MKP-38 Weedless Wedge 2
Installation and maintenance tips
- Replace damaged drive pins and nuts during installation to prevent slippage.
- Inspect blades for nicks after use and balance if necessary to avoid vibration.
- Store spares in a dry place to prevent corrosion and ensure quick swaps on water.
FAQ
- Q: Will a weedless prop make my motor faster?
- A: It can improve push through vegetation and maintain efficiency, which may feel faster in weeds.
- Q: Do all trolling motors use the same prop size?
- A: No, lower-unit diameter and drive pin size vary; confirm fit before purchase.
- Q: Can I mix different brands?
- A: Some props fit multiple brands; verify compatibility with your motor model and serial prefix.
- Q: How do I choose between a three-blade and a two-blade design?
- A: Three-blade props provide smoother thrust and control; two-blade designs often offer higher speed and quicker acceleration in open water.
