Mercury Marine OEM Power Steering Component
Mercury 897643A01 Verado Gen A/B Power Steering Damper Hose
The Mercury 897643A01 Damper Hose is used in Mercury Verado Generation A and Generation B hydraulic power steering systems.
This hose installs on the pressure side of the Verado power steering system between the helm-to-pump pressure hose and the power steering pump. It is used to help dampen hydraulic pulsation and steering-system noise while maintaining the proper pressure-side connection to the pump.
Part Type: Power Steering Damper Hose
Manufacturer: Mercury Marine
OEM or Aftermarket: OEM
Application: Mercury Verado Gen A / Gen B Power Steering Systems
System Location: Pressure Side - Helm Hose to Power Steering Pump
Manufacturer Item #: 897643A01
OEM and Cross Reference Numbers
| Reference Type | Part Number | Manufacturer |
|---|---|---|
| OEM Part Number | 897643A01 | Mercury Marine |
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.
This part is intended for Mercury Verado Generation A and Generation B power steering systems. Mercury Gen C power steering systems use a different pump and hose configuration.
When repairing an existing system, confirm the steering generation and existing hose configuration before ordering.
Compatible Applications
| Brand | Engine / System Family | Steering Generation | Application |
|---|---|---|---|
| Mercury Marine | Verado | Gen A | Hydraulic Power Steering System |
| Mercury Marine | Verado | Gen B | Hydraulic Power Steering System |
Mercury Verado engines can use different power steering configurations depending on the steering generation and rigging. Identify whether the boat has a Gen A, Gen B, or later Gen C steering system before ordering steering components.

- Use the correct Mercury-approved steering fluid and properly bleed the hydraulic steering system after opening a hydraulic connection.
- Confirm all hydraulic fittings are secure and check the completed system for leaks before operating the boat.
Key Features and Benefits

- Gen A / Gen B Application: Used with earlier Mercury Verado hydraulic power steering systems.
- Pressure-Side Installation: Installs between the pressure hose and the Verado power steering pump.
- Steering Noise Control: Helps dampen hydraulic pulsations that can contribute to steering-system noise.

FAQ
What does Mercury part number 897643A01 fit?
The 897643A01 damper hose is used in Mercury Verado Generation A and Generation B hydraulic power steering systems.
Where does the 897643A01 hose install?
It installs on the pressure side of the steering system between the helm-to-pump pressure hose and the Mercury Verado power steering pump.
What does the Verado power steering damper hose do?
The damper hose helps absorb hydraulic pressure pulsations in the pressure-side steering circuit and can help reduce steering-system noise.
Can the pressure hose connect directly to the Verado power steering pump?
The pressure-side hose can connect to the pump in applicable Gen A / Gen B configurations, but the 897643A01 damper hose is recommended between the pressure hose and pump to help minimize steering-system noise.
Does 897643A01 fit Mercury Verado Gen C power steering systems?
This listing is for the Gen A / Gen B steering configuration. Gen C systems use a different pump and hose arrangement, so verify your steering generation before ordering.
