EMP Power Trim Cylinder Seal Kit 58-08211 for Mercruiser Power Trim Cylinders

The EMP Power Trim Cylinder Seal Kit, part number 58-08211, is built to restore hydraulic seal integrity in Mercruiser power trim cylinders. As trim cylinder seals age they harden and lose their sealing ability, letting trim fluid weep past the piston and rod and causing the drive to lose trim position or trim slowly. This kit supplies the seals needed to rebuild the cylinder and stop that leakage, returning the trim system to proper holding pressure. It is a compact, lightweight kit at just 0.031 pounds, sized for direct fitment into the trim cylinder assembly rather than a full replacement cylinder purchase. Rebuilding with a dedicated seal kit is a cost-effective way to address a leaking or soft-trimming Mercruiser power trim cylinder without replacing the entire cylinder body. Because it is manufactured to the original cylinder's seal dimensions, it installs into the existing bore and hardware during a standard cylinder rebuild.
