Description
Size 17 Shear Pins (5/Bx) | Boat Supply Store
This 5-pack of Size 17 shear pins from HANDI-MAN MARINE provides critical protection for outboard motor drive systems. Designed to fracture under excessive torsional load, these pins prevent costly damage to gears and propeller shafts during impacts with submerged objects. They are specifically engineered for outboard motors requiring a 1/4-inch diameter by 1.5-inch length pin, ensuring proper shear point functionality in diverse marine environments like the Gulf Coast or the Texas Intracoastal Waterway.

Common Concerns Answered
What happens if I use the wrong size shear pin?
Using an incorrectly sized shear pin can lead to either premature shearing under normal operating loads, causing unintended downtime, or a failure to shear during a significant impact, resulting in severe damage to your propeller, gearbox, and drive shaft.
How often should shear pins be inspected or replaced?
Shear pins should be visually inspected for signs of wear or damage before each outing. Replacement is necessary if the pin has sheared, or if any corrosion or deformation is observed, as they are sacrificial safety components.
Can a sheared pin cause immediate operational problems?
Yes, a sheared shear pin will prevent the propeller from engaging with the drive shaft, resulting in the engine over-revving without propulsion. This requires immediate replacement of the pin before further operation can occur.
Frequently Asked Questions
What specific outboard motor sizes are these Size 17 shear pins generally compatible with?
Size 17 shear pins are typically designed for specific outboard motor models. Consult your outboard motor's owner's manual to confirm compatibility with a 1/4-inch diameter by 1.5-inch length shear pin.
Are these shear pins made from a material designed to break at a specific force?
Yes, shear pins are manufactured from materials that yield and fracture at a predetermined torsional load, acting as a safety fuse for your outboard's drive system.
What is the precise measurement of a 'Size 17' shear pin in imperial units?
A Size 17 shear pin typically has a diameter of 1/4 inch and a length of 1.5 inches.
How do I properly install a new shear pin?
Remove the old pin and any debris, then insert the new shear pin through the propeller shaft and the corresponding hole in the drive shaft. Secure it according to your outboard's manual, usually with a cotter pin.
What is the advantage of buying shear pins in a pack of five?
Purchasing a 5-count pack ensures you have spares readily available, preventing extended periods of inactivity on the water should a pin shear unexpectedly during a fishing trip or transit.
