Mercury 897643A01 Verado Gen A/B Power Steering Damper Hose

OEM and Cross Reference Numbers

What This Part is Used For

The 897643A01 damper hose is part of the pressure side of a Mercury Verado hydraulic power steering system. It connects between the pressure-side steering hose and the power steering pump.

In a typical Gen A / Gen B Verado installation, hydraulic hoses run between the steering helm and the electrically assisted power steering pump. The 897643A01 is installed at the pump on the pressure side of the system and helps dampen pressure pulsations that can contribute to steering-system noise.

It is commonly replaced when repairing or refreshing an original Mercury Verado Gen A or Gen B power steering system, particularly when replacing damaged, leaking, deteriorated, or previously removed steering hoses.
