Sierra 18-2463 Rear Trim Cylinder Anchor Pin Kit, Replaces 17-14872A1, MerCruiser R/MR/Alpha One 1983-90

The Sierra 18-2463 is a rear trim cylinder anchor pin kit built for MerCruiser R, MR, and Alpha One stern drives (1983-90) with Serial No. 6225577 and up. Each kit is packaged with 2 anchor pins, giving you the correct hardware to secure the rear trim cylinder mounting points without having to source individual pins. This is a rear-specific kit -- it is not designed as a combined front-and-rear solution, so confirm your drive's serial number and application before ordering. Buyers replacing worn, corroded, or damaged anchor pins on the trim cylinder can use this kit as a direct equivalent for the OEM Mercury Marine numbers it replaces. The kit ships in white and is sold as a complete 2-pin package to cover the rear anchor points in one purchase. For MerCruiser owners who need both front and rear anchor pins together, particularly on Alpha One Gen II drives, a separate kit (18-2464) covers that broader application under a different part number -- the 18-2463 covers the rear application only.
