Find the Correct Mercury Outboard Part
Mercury outboard parts can vary by horsepower, engine family, model year, and serial number range. If you are unsure which component fits your engine, use the OEM parts lookup to locate the original Mercury part number from an engine diagram.
Once you have the OEM part number, search Pro Marine to find available genuine Mercury and aftermarket replacement options.

Flexible Hydraulic Steering Hose Kit
Pro Marine PROHHOSE Hydraulic Steering Hose Kit
The Pro Marine PROHHOSE Hydraulic Steering Hose Kit is designed for marine hydraulic steering applications and is available in hose lengths from 1 foot to 30+ feet.
These flexible hydraulic steering hoses are compatible with many standard hydraulic steering systems including Pro Marine, SeaStar®, Uflex®, and similar front-mount hydraulic steering setups.
What Hydraulic Steering Hoses Do
Hydraulic steering hoses transfer steering fluid between the helm pump and steering cylinder. As the steering wheel is turned, hydraulic pressure moves through the hoses to operate the steering cylinder and turn the outboard engine.
Proper hose length and routing are critical for smooth steering operation, engine movement, jack plate travel, and safe hydraulic steering performance.
