So this is one of those specific marine parts that you might not think about until you need it. These tab washers are made from stainless steel, which is crucial for marine applications where corrosion resistance is everything. They're designed specifically for Mercury and Mariner outboards in the 30-65 horsepower range. The part numbers are 14-816629Q, 14816629Q, and 710-14-816629Q if you need to cross-reference with your existing parts. They come in a pack of two, which is handy because these are the kind of small components that can easily get lost during maintenance or repairs. Tab washers are used to secure nuts and bolts in place by bending the tabs against the fastener and adjacent surface, preventing loosening from vibration - something that's super important in marine engines where constant vibration is just part of the deal. The stainless steel construction means they won't rust or corrode quickly, even in saltwater environments. If you're doing maintenance on your Mercury or Mariner outboard and need to replace worn or damaged tab washers, having the correct OEM-style part ensures proper fit and function. They're small, inexpensive components, but using the right tab washer can prevent bigger problems down the line by keeping critical fasteners securely in place. Always good to have a couple spares in your marine toolkit just in case.
