Mercury Trim Roller Overhaul Kit (87399A2)

The Mercury Trim Cylinder Overhaul Kit (87399A2) is a genuine overhaul kit designed to restore the trim cylinder in Mercury outboard and sterndrive systems to a sound, leak-proof, and efficient condition. The trim cylinder hydraulically adjusts the boat's engine angle, optimizing the waterline and improving ride performance. Over time, O-rings, gaskets, and other sealing elements can wear or harden; this kit enables the quick and accurate refurbishment of these parts.

The 87399A2 overhaul kit includes high-strength seals, O-rings, and necessary mounting components that meet Mercury OEM quality standards. Correct part replacement prevents hydraulic leaks, restores trim cylinder performance, and returns the precision of the trim control system. Using this kit during periodic maintenance helps prevent loss of control, slow trim response, and hydraulic performance degradation that can be caused by worn parts.
