Quicksilver Power Trim Hydraulic Hose Port Side

The Quicksilver 32-864959 is a genuine OEM hydraulic hose engineered for MerCruiser power trim and tilt systems. This port-side hydraulic line routes from the trim pump connector block to the port trim cylinder and carries down-pressure fluid, enabling smooth and controlled sterndrive trim operation. As an authentic Mercury/Quicksilver factory part, it meets the exacting dimensional and pressure tolerances required for leak-free, long-lasting service in demanding marine environments.

This hose is a critical component in maintaining proper trim and tilt function. When replacing trim cylinder hoses, it is recommended to service both the port and starboard lines simultaneously for optimal system performance. Use with genuine Quicksilver Power Trim and Steering Fluid for best results.
