This replacement allows customers to service an existing Gen A or Gen B steering system without purchasing all the additional components required for a complete Gen C conversion.
Important: Installation requires reusing the original case from your existing power steering pump.
Warranty: 1 year. Warranty coverage is void if gelled power steering fluid is found inside the pump. See the important steering system inspection and warranty information below before installing your replacement.
IMPORTANT INFORMATION BEFORE REPLACING YOUR VERADO POWER STEERING PUMP
Why Mercury Verado Power Steering Pumps Fail
One of the primary causes of premature Verado power steering pump failure is overheating caused by restricted hydraulic fluid flow.
A problem we frequently encounter is Mercury power steering fluid becoming thick, gel-like, or contaminated. This material can accumulate inside the hydraulic steering system, particularly in the steering cylinder, restricting the movement of hydraulic fluid.
As the steering cylinder becomes restricted, the power steering pump must work harder to move hydraulic fluid through the system. This increased workload can cause the pump to overheat, operate under excessive strain, and eventually fail.
Replacing the Pump Alone May Not Fix the Problem
If the original pump failed because of restricted hydraulic flow or gelled steering fluid, installing another pump without addressing the underlying problem can cause the replacement pump to overheat and fail as well.
Before installing a replacement pump, inspect the steering cylinder, hoses, fluid reservoir, and hydraulic system for gelled fluid, contamination, or restrictions. Correct any problems before operating the replacement pump.
Watch Our Verado Power Steering Repair Video
Watch our video for information about Verado steering system problems and servicing the steering cylinder. Understanding the condition of the hydraulic system before replacing the pump can help prevent another failure.
IMPORTANT WARRANTY WARNING
WARRANTY WILL BE VOID IF GELLED POWER STEERING FLUID IS FOUND INSIDE THE PUMP.
The replacement pump must be installed into a properly functioning hydraulic steering system. Gelled fluid, contamination, or restrictions in the steering cylinder or hydraulic lines must be addressed before installing the replacement pump. Failure to correct these conditions can result in overheating and premature pump failure.

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.

What This Steering Cylinder Seal Kit is Used For
The Pro Marine 2700P Steering Cylinder Seal Kit is designed for resealing compatible Mercury Verado hydraulic steering cylinder assemblies.
Hydraulic steering cylinders use internal seals and O-rings to help maintain hydraulic pressure and prevent fluid leakage.
Over time, these components may become worn or damaged, potentially allowing hydraulic fluid leakage or reduced steering performance.
Replacing worn seals during steering cylinder service can help restore proper sealing when the cylinder and other components remain in serviceable condition.
Common Symptoms and Replacement Reasons
- Hydraulic fluid leaking from the steering cylinder
- Visible deterioration or damage to steering cylinder seals
- Loss of hydraulic steering fluid
- Reduced steering performance associated with seal leakage
- Steering cylinder disassembly for inspection or repair
- Seal replacement during steering cylinder service
Important: Steering problems may also be caused by the power steering pump, hydraulic hoses, helm, fluid contamination, or other system components. Replacing steering cylinder seals will not correct every steering problem.
