Sierra Trim Cylinder Pivot Pin 18-2393, Rear, Replaces Mercruiser 17-14872 (R/MR/Alpha)

The Sierra 18-2393 is a rear trim cylinder pivot pin engineered to ground the trim cylinder to the pivot pin shaft on Mercruiser stern drives. It is designed for the rear trim cylinder on R, MR, and Alpha drive units, positioning and securing the cylinder so the power trim and tilt system operates smoothly and reliably. Each package includes one pivot pin, finished in white. When installing this pin, it should be used with Sierra's 18-2702-1 power trim bushing (sold separately), which supports the pin in its bore and reduces wear from repeated trim cycling.

This pivot pin directly replaces Mercruiser 17-14872, so it is a straightforward drop-in for boats and stern drives originally equipped with that OEM part. Sierra manufactures its replacement parts to meet or exceed the specifications of the original equipment they replace, so buyers can expect the same fit and function as the factory pin without paying dealer OEM pricing. Note that the front trim cylinder pivot pin (Sierra 18-2394) is a different part number with different thread specifications, so be sure to order 18-2393 specifically for the rear trim cylinder application.
