Frequently Asked Questions
What is the difference between OEM and aftermarket marine parts?
OEM parts are produced by the original engine manufacturer. Aftermarket parts are replacement parts produced by other manufacturers to fit the same application. Pro Marine provides quality OEM specification aftermarket products for marine maintenance, repair, and rebuild applications.
How do I find the correct inboard or sterndrive parts?
Use your engine model number, serial number, drive model, and horsepower information to confirm fitment. Sterndrive applications may also require the drive serial number for accurate parts matching.
What brands are included in this category?
This category includes Mercruiser, Volvo, OMC, Crusader, Pleasurecraft, Indmar, and Chrysler marine engine applications.
What are common signs my sterndrive needs service?
Common warning signs include overheating, water in gear lube, vibration, difficult shifting, drive noise, poor acceleration, bellows leaks, and excessive corrosion.
Are aftermarket sterndrive and inboard parts reliable?
Yes. Quality aftermarket marine parts are commonly used by marine mechanics and rebuilders. Pro Marine offers OEM specification aftermarket products for many marine engine and sterndrive repair applications.
Tip: Before ordering sterndrive or inboard parts, verify the engine model, serial number, and drive model information whenever possible.

Pro Marine Mercury Low-Pressure Fuel Supply Module Pump
Mercury EFI, Verado, V6 & V8 Low-Pressure Fuel Pump - 883202
The Pro Marine 883202 Electric Fuel Pump is an aftermarket low-pressure fuel pump used inside compatible Mercury Fuel Supply Module (FSM) / Vapor Separator assemblies. It replaces Mercury pump numbers including 8M0062771, 8M0103289, 883202T02 and 883202T1.
Verified applications span a very wide range of Mercury engines, including select 30-150HP EFI outboards, 200-400HP L6 Verado, 3.4L V6, 4.6L V8, Pro XS, SeaPro, Mercury Racing, and 4.5L / 6.2L MerCruiser, MIE and TowSports engines.
This is the low-pressure side of the fuel system. On many applications it works with a separate high-pressure pump inside the same Fuel Supply Module.

Mercury used several Fuel Supply Module and Vapor Separator configurations within the same horsepower families.
Always verify your engine serial number and original fuel pump number. This pump should be used where the application calls for 8M0062771, 8M0103289, 883202T02 or 883202T1.

Opening the Fuel Supply Module to replace a pump? The 7333 seal kit replaces Mercury 8M0133370 and is used to reseal compatible FSM assemblies during service.
What This Fuel Pump is Used For
The low-pressure pump supplies fuel into and through the Mercury Fuel Supply Module or Vapor Separator. Its job is to keep the module supplied with enough fuel for the high-pressure portion of the EFI system.
On applications with separate low- and high-pressure pumps, the low-pressure pump does not create the final injection pressure. Instead, it keeps the reservoir supplied so the high-pressure pump can deliver the fuel pressure required by the injectors.
Low-Pressure vs. High-Pressure Fuel Pump
| Pump Type | Function |
|---|---|
| 883202 Low-Pressure Pump | Moves fuel into and through the Fuel Supply Module and maintains fuel supply for the high-pressure side. |
| High-Pressure Pump | Produces the higher pressure required by the engine's EFI system. The correct high-pressure pump varies by engine family and serial range. |
Common Signs of Low-Pressure Pump Problems
- Hard starting or extended cranking
- Fuel Supply Module does not stay adequately supplied with fuel
- Loss of power under acceleration
- Engine hesitation under load
- Engine runs at low RPM but loses power at higher RPM
- High-pressure pump becomes fuel-starved
- Low-pressure fuel-delivery test is below specification
- Pump fails electrical testing
Why Test Both Fuel Pumps?
A low-pressure pump problem can mimic a high-pressure pump failure. If the low-pressure side cannot keep the FSM supplied with fuel, the high-pressure pump may be unable to maintain proper pressure even if the high-pressure pump itself is operating correctly.
Diagnose fuel supply and fuel pressure before replacing parts. When the FSM is opened, inspect the other pump, wiring, electrical connectors, internal fuel passages and seals while the module is accessible.
