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.

View Gen A/B Power Steering PumpInstallation and Service Tips
- Install the 897643A01 on the pressure side of the Gen A / Gen B Verado power steering system.
- The damper hose is positioned between the helm-to-pump pressure hose and the power steering pump.
- Inspect the surrounding steering hoses and fittings for leaks, cracking, deterioration, or damage whenever servicing the pump.
- 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
- OEM Mercury Component: Genuine Mercury Marine steering-system part.
- 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.
- Direct Replacement: Ideal when replacing an existing 897643A01 during steering-system service.
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.
Should I inspect this hose when replacing the power steering pump?
Yes. Whenever the power steering pump is being serviced, inspect the damper hose, pressure hose, return hose, fittings, and surrounding hydraulic components for leaks or deterioration.

Replacement Hydraulic Steering Cylinder
Pro Marine 350-HSTEER-CYL Hydraulic Steering Cylinder
The Pro Marine 350-HSTEER-CYL Hydraulic Steering Cylinder is the replacement steering cylinder used with the Pro Marine 350-HSTEER hydraulic steering system. It is designed for high-horsepower single outboard setups where smooth, controlled steering response is critical.
This is the cylinder only. Helm pump, hoses, steering fluid, and fill/bleed accessories are sold separately unless purchased as part of the complete 350-HSTEER system.
What This Cylinder Is Used For
The steering cylinder converts hydraulic pressure from the helm pump into side-to-side movement at the outboard engine. It is the component that physically moves the engine when you turn the steering wheel.
If your current cylinder is leaking, damaged, binding, or worn, replacing it can restore proper steering control and improve the overall feel of the system.

25cc Hydraulic Steering Helm Pump
Pro Marine 350-HELM-025 Hydraulic Helm Pump
The Pro Marine 350-HELM-025 Hydraulic Helm Pump is a 25cc hydraulic steering helm designed for smooth, controlled steering response on modern outboard boats.
This helm is compatible with many standard hydraulic steering systems, including Pro Marine, SeaStar®, Uflex®, and other similar front-mount hydraulic steering setups.
What a Hydraulic Helm Pump Does
The helm pump is the core component of a hydraulic steering system. When the steering wheel is turned, the helm creates hydraulic pressure that moves fluid through the hoses and steering cylinder to turn the engine.
A properly matched helm pump helps provide predictable steering feel, reduced steering effort, and smooth handling at both low and high speeds.

37cc Hydraulic Steering Helm Pump
Pro Marine 350-HELM-037 Hydraulic Helm Pump
The Pro Marine 350-HELM-037 Hydraulic Helm Pump is a 37cc hydraulic steering helm designed for smooth, responsive steering control on high-horsepower outboard boats.
This Pro Marine helm is designed for the 350-HSTEER system and is compatible with many standard hydraulic steering systems, including Pro Marine, SeaStar®, Uflex®, and other similar front-mount hydraulic steering setups.
What a 37cc Helm Pump Does
The helm pump creates the hydraulic pressure that moves fluid through the steering hoses and into the steering cylinder. When you turn the wheel, the helm controls how much fluid is moved through the system, which directly affects steering feel and wheel turns lock-to-lock.
A 37cc helm moves more fluid per steering wheel turn than smaller 25cc or 30cc helms, which can create quicker steering response and fewer turns lock-to-lock when matched with the correct hydraulic steering cylinder.
