The Sierra Trailering Clips, part number 18-9099, are replacement clips used to secure the outdrive of a Mercury Marine sterndrive during trailering. Sold as a pair, each clip has an inside diameter of 3/4 inch and a length of 11 1/8 inches, sized to fit the trailering clip application on Alpha One, Alpha Generation II, Bravo I, Bravo II, Bravo III, and Blackhawk drives. These clips are a direct cross-reference to a wide range of Mercury Marine OEM part numbers, making it easy to find the correct replacement using whichever number is printed on the old clip or listed in service documentation. Trailering clips are a wear item that should be inspected and replaced when worn, bent, or corroded, since a failed clip can allow the outdrive to shift on the trailer during transport.
