Product Details
This starboard-up hydraulic trim hose is an aftermarket replacement for the hose used in power-trim systems. Catalog references identify 3853855 as a starboard-up trim hose in selected Evinrude Quiet Rider transom-bracket assemblies, including documented 1993–1994 two-stroke applications from 100 HP through 175 HP. Trim-hose listings also cover Volvo Penta SX-C, SX-R, and SX-S sterndrive applications.
The hose connects the trim manifold to the trim cylinder for the starboard-side “up” circuit. Because hose routing, fittings, model designations, and production ranges can vary, verify the original hose, connection orientation, engine or sterndrive model, and manufacturer part number before ordering.
- Starboard-side “up” trim-hose application.
- Connects the hydraulic trim manifold to the trim cylinder.
- Aftermarket replacement for selected applications using 3853855.
- Black hose assembly.

Installation Notes
- Place the boat and outboard or sterndrive in a stable position and secure the drive according to the manufacturer’s safety procedure.
- Relieve hydraulic pressure before loosening any trim-hose connection.
- Place absorbent rags or an oil pan beneath the connections to collect hydraulic fluid.
- Using suitable flare-nut or line wrenches, disconnect the hose from the trim manifold and cylinder without damaging the fittings.
- Compare the replacement hose with the original for routing, length, fitting style, and orientation before installation.
- Thread both fittings by hand first to prevent cross-threading, then tighten them to the manufacturer’s specified torque. Do not overtighten.
- Refill the trim system only with the fluid specified by the equipment manufacturer, then cycle the trim system several times to remove trapped air.
- With the system at rest, inspect both connections for leaks and verify smooth trim operation before returning the vessel to service.
Troubleshooting & FAQ
Is this the correct hose for my engine?
This is the starboard-side “up” hose. Documented catalog examples include selected 1993–1994 Evinrude two-stroke Quiet Rider applications from 100 HP through 175 HP, while trim-hose application listings also include Volvo Penta SX-C, SX-R, and SX-S families. Always compare your exact model, year, hose position, fittings, and original part number before ordering.
What is the difference between an “up” and “down” hose?
Trim systems use separate hydraulic circuits for raising and lowering the drive. This product is identified for the starboard-side “up” circuit and should not be substituted for a down hose or a port-side hose unless the manufacturer’s parts information confirms the interchange.
My original part number is not 3853855. Will this fit?
Do not rely on a number alone. Confirm the hose position, fitting style, routing, length, and exact engine or sterndrive model. If your original number differs, contact support with clear photos and the complete model information before ordering.
What are common symptoms of a bad trim hose?
Typical symptoms include visible hydraulic-fluid leakage, slow or uneven trim movement, a spongy response, or the drive gradually drifting down after it has been raised. Inspect the hose and fittings before operating the vessel.
Do I need special tools for installation?
Flare-nut or line wrenches are recommended to reduce the risk of damaging the fittings. Use appropriate supports and follow the manufacturer’s pressure-relief and bleeding procedures. Professional marine-mechanic installation is recommended.
How often should trim hoses be replaced?
There is no universal replacement interval. Inspect trim hoses at least annually and before extended use for leaks, abrasion, cracking, swelling, or hardened material. Replace the hose at the first sign of damage.
Is this an aftermarket or OEM part?
This listing is for an aftermarket replacement component, not an original equipment manufacturer part. It is intended to replace the specified starboard-up trim-hose application when the exact fitment has been confirmed.
How fast is shipping?
Typical international transit is 5–15 days. Standard shipping is free, and expedited options appear at checkout when available for the destination.
What is the warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal use. Returns are accepted within the standard return period for unused items in original condition. Contact support for return instructions and order assistance.
Safety & Important Info
- Verify the exact hose position, model, year, fittings, routing, and original part number before installation.
- Never work beneath an unsupported raised outboard or sterndrive.
- Hydraulic fluid can be under pressure. Relieve system pressure before disconnecting the hose.
- Clean spilled hydraulic fluid promptly and dispose of used fluid according to local regulations.
- This is an aftermarket replacement component, not an OEM part.
- Professional installation by a qualified marine mechanic is strongly recommended.
