GRONGU 2092600 Compatible with Minn Kota Motors
Best for builders and replacement planners who need reliable, corrosion-resistant pins for a range of Minn Kota MKP models (MKP-2 to MKP-37). The 2092600 stainless steel pins are designed to minimize wear and provide dependable operation on 55–65 lb thrust motors. This option is especially suited for anglers who rely on steady, quick replacements in varying water conditions. A caution: note that MKP-2 Endurance models are not supported by this pin type, so verify model compatibility before purchase.

Best for redundancy and bulk replacements. This 8-piece stainless steel set covers 2092600 pins with robust hardness and wear resistance, suitable for MKP-2 through MKP-37 models and similar trolling motors. Designed to secure the prop drive and minimize downtime. A limitation: ensure you handle pins with gloves during installation to protect hands and maintain alignment.
PalpitateC 2262658 Prop Pins for MKP Series
Best for MKP 33 and MKP 38 Weedless Wedge 2 installations and similar high-thrust motors (80–112 lb). The 2262658 pins come in a 3-pack, offering ready replacements for anglers who run larger Minn Kota setups. Choose this if you operate weedless models and want dependable, corrosion-resistant drive pins. Caution: verify exact motor model compatibility before purchase to avoid misfit.
eMagTech 2Pcs Shear Pins 17-95372
Best for Mercury and Mariner outboards (2.2–3.5 HP ranges) needing a safety pin that prevents drive shaft damage when the prop is blocked. The 17-95372 model is a precise fit for specific Mercury-Mariner configurations and acts as a crucial safety device during operation. A limitation: verify engine model compatibility since this pin targets particular Mercury/Marnier two-stroke and four-stroke variants.

This 4-pack is designed for Minn Kota MKP-2 through MKP-37 compatibility, making it suitable for boaters who want ready substitutes without frequent ordering.

EUSTREER 8 Pcs 2092600 Pins
Best value package for daily use. The 8-piece set covers MKP-2 through MKP-37 pins with stainless steel construction for durability and corrosion resistance.

UANOFcn 1795372 Propeller Shear Pin Kit
Best for Mercury, Mariner, Nissan, and Tohatsu models needing a split-pin kit alongside standard shear pins. This kit covers multiple engine configurations and includes split pins for secure assembly. Consider this if your maintenance routine includes more than one engine type, but verify model compatibility to ensure you are purchasing the correct kit.
Buying Guide: Key Considerations For Shear Pins
- Model compatibility: Always verify the pin part number (e.g., 2092600) and the specific Minn Kota MKP model (MKP-2 through MKP-37) or Mercury/Nissan compatibility before purchase.
- Material and durability: Stainless steel pins offer corrosion resistance and longer life in salt or brackish water environments.
- Pack quantity: Choose a pack size that matches how often you replace pins or whether you want spare parts on hand for quick swaps on the water.
- Installation requirements: Most pins require gloves and no special tools; however, confirm any model-specific instructions to avoid misalignment or damage during installation.
- Safety considerations: A properly installed shear pin protects the drive train by breaking under excessive load; ensure the replacement pin matches the engine’s design and is the correct shear rating for your motor.
- Performance trade-offs: While higher compatibility is convenient, some models do not fit certain MKP variants (e.g., MKP-2 Endurance is not compatible with some 2092600 pins). Double-check model lists.
- Maintenance context: Keep a ready set for saltwater and freshwater use, as corrosion can affect pin integrity over time.
Frequently Asked Questions
- What is a shear pin, and why is it important for boat motors?
A shear pin is a sacrificial pin designed to break under excessive load to protect the propeller and drive shaft from damage during obstructions or impact.
- How do I know which shear pin fits my Minn Kota MKP motor?
Check the model number of your motor and reference the pin’s compatibility list (e.g., 2092600 pins fit MKP-2, MKP-3, MKP-6, MKP-7, MKP-25, MKP-37; some models are not supported).
- Can I use stainless steel shear pins for saltwater fishing?
Yes. Stainless steel provides better corrosion resistance, which is beneficial in saltwater environments, but rinse and dry after use to extend life.
- Should I replace all pins at once or one by one?
Carry spare pins and replace only the pin that has failed or worn out. If multiple pins show wear, replace them in a timely manner to avoid downtime.
- Are there any safety precautions during installation?
Wear gloves to protect hands during installation and ensure the pin is properly seated and aligned with the prop shaft to avoid binding.
- Do these pins work with Mercury or Mercruiser engines?
Some pins are designed for Mercury/Mariner models (e.g., 17-95372) and should be used only with compatible engines as specified by the product listing.
