Part Number: 22187385
Brand: Volvo Penta
Official Product Type: Hydraulic Trimming Cylinder – Port Side, 52° Full Tilt
System: Sterndrive Power Trim
Position: Port (left-hand side)
Tilt Range: 52° full tilt

Overview

The Volvo Penta 22187385 is the genuine OEM port-side hydraulic trimming cylinder for SX-A, DPS-A, and DPS-B sterndrive power-trim systems. This is the 52° full-tilt version, with a fully extended length of approximately 23-13/16”. It hydraulically raises and lowers the port side of the sterndrive to control running angle, bow attitude, and drive position.

This cylinder is sold individually. The port and starboard cylinders are different components — 22187385 is the port (left-hand) side only. The matching starboard cylinder is 22187386.

Compatible Applications

• Volvo Penta SX-A sterndrive (52° full-tilt trim system)
• Volvo Penta DPS-A sterndrive (52° full-tilt trim system)
• Volvo Penta DPS-B sterndrive (52° full-tilt trim system)

Volvo Penta SX-A and DPS-A/B trim systems were also produced with 32° and 42° cylinder configurations. Confirm the transom shield and trim system configuration before ordering — do not order by drive model alone.

Serial Number & Fitment Notice

Three identification points must all match before ordering: port side + 52° tilt range + SX-A/DPS-A/DPS-B drive family. Volvo Penta used shorter 32° and 42° trim cylinders on related transom systems, and the port and starboard cylinders are not interchangeable. Confirm drive model, side, tilt angle, and serial number before ordering.

Superseded Part Numbers

• 3840326 — earlier Volvo Penta reference for this port-side cylinder configuration
• 3889954 — previous Volvo Penta part number, superseded by 22187385
• 22187385 — current OEM part number

Dimensions & Weight

• Fully extended length: approximately 23-13/16”
• Tilt range: 52°
• Approximate weight: 3.5 kg (hydraulic cylinder assembly)

When to Replace

Replace the trim cylinder if it develops hydraulic leakage, a scored or corroded piston rod, excessive play at the mounting points, damaged hydraulic fittings, or difficulty maintaining the sterndrive at the selected trim position. Inspect both port and starboard cylinders at the same service — if one is worn, the other is likely at a similar service age.

Installation Notes

Inspect the trim hoses, hydraulic fittings, mounting pins, clamps, and surrounding hardware before installing the replacement cylinder. Current replacement assemblies include a trim-hose O-ring and brass ferrule. After installation, operate and bleed the trim system per the applicable Volvo Penta service procedure. Verify smooth travel through the complete 52° tilt range and check all connections for leakage before returning the vessel to service.

Technical FAQ

Q: Is 22187385 the port or starboard cylinder?
A: 22187385 is the port (left-hand) side trimming cylinder. The starboard cylinder is 22187386.

Q: What is the tilt angle of this cylinder?
A: 52° full tilt, with a fully extended length of approximately 23-13/16”. Volvo Penta also used 32° and 42° cylinders on related SX-A and DPS-A transom systems — confirm your trim system configuration before ordering.

Q: Does 22187385 replace 3889954?
A: Yes. 22187385 is the current Volvo Penta OEM part number that supersedes 3889954 and the earlier reference 3840326.

Q: Do I need to replace both cylinders at the same time?
A: Not always required, but recommended if both cylinders are at similar service age. Replacing both at the same service avoids a repeat job shortly after.

Q: What causes trim cylinder failure on SX-A/DPS drives?
A: The most common causes are corrosion on the piston rod (especially in saltwater environments), seal wear from age or contaminated hydraulic fluid, and physical damage to the rod or fittings. Regular anode service and keeping the hydraulic fluid clean extend cylinder life.

Parts Desk Insights

The three identification points for this part are port side, 52° tilt, and SX-A/DPS-A/DPS-B drive family. Do not order by appearance alone — Volvo Penta also used 32° and 42° cylinders on related transom systems, and they look similar but are not interchangeable. If a customer is replacing one cylinder due to a leak, recommend inspecting the starboard cylinder (22187386) at the same time. Also check the trim hoses and hydraulic fittings while the drive is apart — a cylinder replacement is a good opportunity to address any hose wear before it becomes the next service call.
