Troubleshooting & FAQ
Which Volvo Penta drives is this kit compatible with?
This kit is designed for Volvo Penta SX and DP-SM series sterndrives from 1994 and newer. Please refer to the compatibility table for specific model numbers like SX-C, SX-R, and DP-SM.
What are common signs that my trim cylinders need replacing?
Symptoms include a "spongy" or unresponsive trim, visible hydraulic fluid leaks around the cylinder seals or lines, or the sterndrive slowly dropping from a trimmed-up position (known as "bleed-down").
How do I bleed the trim system after installing the new cylinders?
After installation, top off the hydraulic fluid reservoir. Cycle the sterndrive up and down slowly 4-5 times, pausing at the top and bottom of each cycle. This purges air from the system. Re-check and top off the fluid level when finished.
Is this a single cylinder or a pair?
This is a complete kit that includes both the port and starboard (left and right) trim cylinders, along with new hydraulic lines, pins, and seals for a full replacement.
