Caution: Always verify the exact model and pin size (Model 17-95372) before purchasing to ensure proper fit. If your engine uses a different pin specification, this kit may not install correctly.

GRONGU’s 2092600 prop pins are aimed at Minn Kota trolling motors. This 4-pack is a practical choice for anglers who rely on MKP-2, MKP-3, MKP-6, MKP-7, MKP-25, or MKP-37 models. The pins are stainless steel for durability and are positioned as a reliable replacement to restore prop drive function after a pin shears. Best for boaters who want a steady supply of spare pins ready for Minn Kota setups, especially if trolling is a frequent activity.
Limitation: Note that the replacement part does not fit some Endurance MKP variants. Confirm your Minn Kota model before buying to avoid incompatibility.

A practical choice for ongoing seasonal use and spare-part stocking.
Limitation: Verify that the included split pin components suit your gearbox and propeller arrangement to ensure secure fitment during installation.
SG Store 4pcs Pins For Honda Outboards

SG Store’s four-pack targets Honda 4–6 HP engines, with pins sized at 5x25mm. This set emphasizes stainless steel construction for corrosion resistance and long service life.

Use this kit if you want a cost-effective, ready-to-install option for regular maintenance of light trolling or compact boat use.

The eight pins provide a larger spare stock for ongoing maintenance, ideal for frequent users who rely on Minn Kota components. Best for boaters who want redundancy and quick replacements to minimize downtime after a pin shear. The pack includes robust stainless steel pins noted for wear resistance.
Limitation: The extended pack is tailored to MKP-series pins; verify compatibility with your specific MKP model to avoid mismatch.
Buying Guide: Key Purchase Considerations
- What motor model and HP range do you own? Pin size and compatibility vary by manufacturer and horsepower.
- Is stainless steel the right material for your environment? Stainless steel offers corrosion resistance in saltwater and humid conditions but may differ in hardness and tolerances.
- How many spare pins do you need? Some packs include 2 pins, others 4 or 8; select based on maintenance habits and storage space.
- Are you shopping for a specific brand (Mercury, Minn Kota, Honda, etc.) or a universal kit? Brand-specific pins often ensure seamless fit, while universal packs provide broader applicability.
- Do you require additional accessories like split pins or mounting hardware? Some kits bundle split pins for easy installation, while others focus solely on shear pins.
Frequently Asked Questions
- Why do outboard motor shear pins exist? They prevent major damage by breaking under overload when the propeller strikes an obstruction.
- How do I know which pin size to buy? Check your engine’s model number and the pin dimensions (diameter and length) listed by the manufacturer.
- Can I reuse a shear pin? No. Once a shear pin has sheared, replace it with a new one to maintain protective function.
- Are stainless pins suitable for saltwater use? Yes, stainless steel offers good corrosion resistance, but confirm that the grade matches your environment.
- Should I buy a multi-pack or single pack? Multi-packs are convenient for ongoing maintenance and emergencies, especially for frequent users.
- Do these pins affect engine performance when not under load? Shear pins are designed to only engage under overload; normal operation remains unaffected.
