📋 Kit Contents

• Matched 42-degree port and starboard trimming-cylinder assemblies - Volvo Penta kit 22187350
• Hydraulic hoses, seals and mounting pieces - supplied within kit 22187350; separate current numbers are not published in the indexed kit listing

🔌 Function

The cylinders convert hydraulic pressure into controlled drive-angle movement for acceleration, running trim, shallow-water operation and trailer positioning.

⚠️ Common Signs of Failure

• Drive will not raise, lower or hold position
• Hydraulic oil leaks at the rod or hose fittings
• Port and starboard cylinders move unevenly
• Cylinder rod is bent, pitted or corroded
• Internal bypass allows the drive to settle

🛠️ Service Notes

• Raise the drive and support it securely, taking the weight off the cylinder before anything is disconnected — the drive will drop as soon as the cylinder is free
• Have a tray ready for the fluid that comes out when the hydraulic lines are opened, and cap the lines and fittings so no grit gets into the system
• Fit the cylinder with the rod fully retracted; clean and grease the pivot pins and bushes as specified for your drive and use the new pins, clips or fasteners supplied in the kit rather than the old ones
• Refill the trim reservoir with the fluid specified for your system and cycle the drive fully up and down several times with the cap off until the fluid runs free of bubbles, checking the level between cycles
• With the boat afloat, check the cylinders and unions for leaks under load and confirm the drive holds its trim position without creeping
