Pro Marine Mercury Verado Power Steering
Pro Marine Mercury Verado Gen A / Gen B Reman Power Steering Pump 8M0134736P
The Pro Marine 8M0134736P Remanufactured Power Steering Pump is an aftermarket replacement for Mercury Verado Gen A and Gen B power steering systems. It cross references Mercury part numbers 8M0134359 and 8M0134736.
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.

Frequently Asked Questions
Is this a replacement for Mercury Verado Gen A and Gen B power steering pumps?
Yes. Pro Marine 8M0134736P is an aftermarket replacement for compatible Mercury Verado Gen A and Gen B power steering pumps. It cross references Mercury 8M0134359 and 8M0134736.
Do I need to reuse my old pump case?
Yes. This replacement requires the original case from your existing power steering pump.
Why do Mercury Verado power steering pumps overheat?
One common cause is restricted hydraulic fluid flow. We frequently encounter systems where power steering fluid has become thick or gel-like and accumulated inside the steering cylinder. These restrictions can force the pump to work harder, leading to overheating and premature failure.
Can gelled power steering fluid damage a replacement pump?
Yes. If gelled fluid or a restriction remains in the hydraulic steering system, a replacement pump can experience the same excessive workload and overheating that damaged the original pump.
Should I inspect the steering cylinder before replacing the pump?
Yes. Inspect the steering cylinder and hydraulic system for gelled fluid, contamination, and restrictions. Correct any problems before operating the replacement pump.
Does gelled power steering fluid void the pump warranty?
Yes. The warranty is void if gelled power steering fluid is found inside the pump. Inspect and service the hydraulic system before installation to help prevent repeat failure.
Does Pro Marine have a video explaining Verado steering problems?
Yes. Watch our Verado Power Steering Repair Video for additional information about steering system service.
Can I rebuild my existing Verado steering cylinder?
Depending on the cylinder's condition and compatibility, repair may be possible using the Pro Marine 2700P Steering Cylinder Seal Kit . Inspect the cylinder for internal damage before deciding whether to repair or replace it.
Is a remanufactured steering cylinder available?
Yes. Pro Marine offers the 896500R01 Remanufactured Verado Steering Cylinder for compatible applications.
Should I replace my Gen A / Gen B pump or upgrade to Gen C?
Replacing the existing pump may be the simpler option when the remainder of the steering system is serviceable. A Gen C conversion requires additional components and configuration checks. Review our Gen A / Gen B to Gen C Conversion Guide to compare the options.
Where can I find Verado power steering technical information?
Visit the Pro Marine Verado Power Steering Technical Center for steering system information, replacement parts, and technical resources.
Are some Verado steering hoses special order?
Yes. Various helm-to-pump and cylinder-to-helm hose lengths are special-order items. Call Pro Marine USA at 941-721-3000 to confirm availability and order.

Hydraulic Steering System with Tilt Helm
Pro Marine 350-TSTEER Hydraulic Steering System
The Pro Marine 350-TSTEER Hydraulic Steering System is a complete hydraulic steering package with an all-new tilt helm for smooth, responsive steering control on high-horsepower outboard boats.
This universal Pro Marine hydraulic steering system is designed for outboard applications up to 350HP. It includes the main steering components needed for installation, but does not include hydraulic hoses.
What a Hydraulic Steering System with Tilt Helm Does
A hydraulic steering system uses a helm pump, hydraulic fluid, hoses, and a steering cylinder to turn the outboard engine. When the steering wheel is turned, the helm moves fluid through the system and operates the cylinder mounted at the engine.
The tilt helm allows the steering wheel angle to be adjusted for driver comfort while maintaining smooth hydraulic steering response. This is especially helpful on center consoles, bay boats, and performance boats where the operator may switch between seated and standing driving positions.
