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.

EMP High Pressure Fuel Pump 39612
EMP 39612 is an aftermarket electric high pressure fuel pump that replaces Mercury OEM part number 8M0062770. This pump is commonly used inside the Fuel Supply Module on select Mercury 65-150HP EFI outboards and MerCruiser 4.5L and 6.2L MPI engines.
Important Fitment Note
This high pressure fuel pump is not universal. Fitment depends on engine model, serial number, and Fuel Supply Module configuration. Always verify that your original pump or OEM parts diagram calls for Mercury OEM number 8M0062770 before ordering.
Compatible Applications
Because Mercury fuel system fitment can vary by serial range and Fuel Supply Module design, confirm the OEM number from your engine parts diagram before replacing the pump.

Low Pressure Electric Fuel Pump
Many Mercury fuel systems use both a high pressure pump and a separate low pressure pump. If you are servicing the complete fuel supply module or diagnosing fuel delivery issues, check the low pressure pump as well.
View Low Pressure PumpWhat This Part is Used For
The high pressure fuel pump supplies pressurized fuel to the engine fuel injection system. On many compatible Mercury and MerCruiser applications, this pump is located inside the Fuel Supply Module and works with the low pressure side of the system to maintain proper fuel delivery.
EMP 39612 is a popular aftermarket replacement option for Mercury OEM 8M0062770 and is often used as a more affordable alternative to the OEM Mercury high pressure fuel pump.
Common Symptoms of a Failing High Pressure Fuel Pump
The engine may crank longer than normal or struggle to start.
A weak pump may not supply enough fuel under acceleration or load.
The engine may stall when fuel pressure drops below the required range.
A failed pump can prevent the fuel system from reaching proper pressure.
Key Features and Benefits
Aftermarket replacement from Engineered Marine Products for compatible Mercury applications.
Cross references Mercury OEM high pressure fuel pump number 8M0062770.
Used as the high pressure pump inside select Mercury and MerCruiser FSM assemblies.
A more affordable replacement option compared to many OEM fuel pump listings.

OEM Mercury & MerCruiser Oil Drain Plug Seal
Mercury MerCruiser Oil Drain Plug O-Ring 863006
The Mercury MerCruiser 863006 Oil Drain Plug O-Ring is an OEM replacement seal used across a wide range of Mercury outboards, Verado engines, MerCruiser sterndrives, and inboard marine engines.
This O-ring seals the oil drain plug assembly and helps prevent oil leaks during operation and after routine oil service.
Fitment Overview
OEM part number 863006 is used across numerous Mercury and MerCruiser oil drain plug applications. Unlike the drain plug assembly itself, this seal is shared across multiple engine families and marine platforms.
This includes Mercury EFI outboards, Verado engines, V6/V8/V10 outboards, MerCruiser sterndrive engines, and select inboard marine engines.
Compatibility
| Application | Models / Engine Families |
|---|---|
| Mercury EFI 4-Stroke Outboards | 65HP through 150HP EFI models |
| Mercury V6 Outboards | 3.4L V6 175HP and 200HP |
| Mercury V8 Outboards | 4.6L V8 200HP through 300HP |
| Mercury V10 Outboards | 350HP 400HP 425HP models |
| Mercury Racing | 300R 450R 500R Verado applications |
| MerCruiser Sterndrive Engines | Multiple GM-based marine engine platforms |
| MerCruiser Inboard Engines | Select inboard oil drain plug applications |
Always verify fitment using your engine serial number or existing part number before ordering.

| Associated Drain Plug Assembly | 8M0112869 |
| Related Drain Plug Assemblies | 8M0064964, 8M0045813 |
What This O-Ring Is Used For
This O-ring seals the oil drain plug assembly to prevent oil leaks and seepage. Over time, heat cycles, oil exposure, and repeated removal during oil changes can flatten or damage the seal.
- Seals engine oil drain plug assemblies
- Helps prevent oil leaks after service
- OEM Mercury and MerCruiser replacement seal
- Often replaced during routine oil maintenance
Replacing the O-ring during oil service is often the easiest and most affordable way to prevent future leaks.
System Function and Connections
- System Type: Engine lubrication / oil drain system
- Component Type: Oil drain plug O-ring seal
- Associated Components: Oil drain plug assemblies and oil pan drain systems
- Location: Oil drain plug sealing surface
FAQ
What does the 863006 O-ring fit?
It fits many Mercury and MerCruiser oil drain plug applications including EFI outboards,
Verado engines, V6/V8/V10 outboards, and select sterndrive and inboard engines.
Can I replace just the O-ring instead of the entire drain plug assembly?
Yes. If the drain plug assembly itself is still in good condition and only the seal is leaking,
replacing the O-ring is often the simplest repair.
When should I replace the full drain plug assembly?
Replace the entire assembly if the plug is cracked, stripped, damaged,
or leaking around the plug body itself.
What drain plug assembly commonly uses this O-ring?
One common associated assembly is the Mercury
8M0112869 Oil Drain Plug Assembly
