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.
