Genuine Mercury Marine Gearcase Drain Plug Seal
Mercury 8M0082880 Lower Unit Drain Plug Seal
Mercury Marine 8M0082880 is an OEM gearcase drain plug seal / washer used on select Mercury, Mariner and related outboard applications. Cross-reference information also connects this seal to select Johnson, Evinrude, Nissan and Tohatsu outboards.
This small but important seal installs at the gearcase drain screw and helps keep gear lubricant inside the lower unit while preventing water from entering around the drain plug.
Drain plug seals should be inspected whenever the lower-unit gear lube is serviced and replaced when worn, damaged or as specified during routine gear-lube maintenance.
Part Type: Gearcase Drain Plug Seal / Washer
Manufacturer: Mercury Marine
Manufacturer Item #: 8M0082880
OEM or Aftermarket: OEM
Color: Blue
Application: Select Outboard Gearcase Drain Screws
Pro Marine Item #: 8M0082880
OEM and Cross Reference Numbers
Depending on manufacturer, catalog and aftermarket brand, this drain plug seal may be found under several different part numbers.
| Cross Reference Numbers |
|---|
| 18-60103, 18-72656, 332600060, 332600060M, 332600061, 332600061M, 5040030, 8M0075255, 8M0082880, 8M0188617, 898101080, 95220, 95220010 |
When replacing an existing seal, compare the original part number and verify the engine model or serial number before ordering.
What This Part is Used For
The 8M0082880 seal fits around the applicable lower-unit drain/fill screw. When the screw is tightened, the seal helps create a reliable barrier between the gearcase and the surrounding water.
A properly sealing drain screw is important because the lower unit needs to:
- Keep gear lubricant inside the gearcase
- Help prevent water from entering through the drain screw
- Maintain a reliable seal after routine gear-lube service
A drain plug seal is inexpensive compared with the gears, bearings and other components inside a lower unit.
Inspect the seal whenever the gear lube is changed. Replace a seal that is worn, damaged, distorted or otherwise unsuitable for reuse.
Mercury and Mariner Fitment
Mercury 8M0082880 appears in gearcase, driveshaft-housing and maintenance diagrams across a number of small Mercury outboard families. Applications shown in the supplied Mercury catalog information include the following.

| 15 HP EFI 2-Cylinder 333cc | 0R833820-Present |
| 15 HP EFI SeaPro 2-Cylinder 333cc | 0R833820-Present |
| 20 HP EFI 2-Cylinder 333cc | 0R833820-Present |
| 25 HP EFI 3-Cylinder | 1R154758-Present |
| 25 HP EFI SeaPro 3-Cylinder | 1R154758-Present |
| 25 HP EFI Jet 3-Cylinder | 1R154758-Present |
| 30 HP EFI 3-Cylinder | 1R154758-Present |
Additional earlier Mercury applications are shown in the supplied catalog diagrams, including select carbureted 8, 9.9, 10, 15, 20 and 25 HP models and earlier 25/30 HP EFI applications. Because Mercury used multiple gearcase configurations within some horsepower families, verify the engine serial number and gearcase diagram when working with an earlier engine.
Johnson and Evinrude Fitment
Cross-reference data also identifies this seal for numerous Johnson and Evinrude 3-15 HP four-stroke model-number applications. Matching model families include:
| Brand | Horsepower | Model Families |
|---|---|---|
| Johnson | 3 HP | B3R4, B3RG4 |
| Johnson | 4 HP | B4R4, B4RG4, B4RGL4, B4RL4 |
| Johnson | 6 HP | B6R4, B6RG4, B6RGL4, B6RL4, B6RX4 |
| Johnson | 10 HP | B10EGL4, B10EL4, B10PL4, B10PX4, B10R4, B10RG4, B10RGL4, B10RL4, B10TEL4, B10TPL4, B10TPX4 |
| Johnson | 15 HP | B15PL4, B15R4, B15RG4, B15RGL4, B15RL4, B15TE4, B15TEL4 |
| Evinrude | 3 HP | E3R4, E3RG4 |
| Evinrude | 4 HP | E4R4, E4RL4 |
| Evinrude | 6 HP | E6R4, E6RG4, E6RGL4, E6RL4, E6RX4 |
| Evinrude | 10 HP | E10EL4, E10PGL4, E10PL4, E10PX4, E10R4, E10RG4, E10RGL4, E10RL4, E10TEL4, E10TPL4, E10TPX4 |

The complete model suffix matters. When identifying this seal by Johnson or Evinrude model number, compare the complete engine model designation with the parts catalog rather than relying only on horsepower.
Nissan and Tohatsu Applications
Cross-reference information also shows this drain-plug seal across a broad range of older Nissan and Tohatsu outboard gearcase applications.
Supplied application data includes Nissan engines from approximately 2 HP through 140 HP across various 1996-2008 applications, including 2.5, 3.5, 4, 5, 6, 8, 9.8, 9.9, 15, 18, 20, 25, 30, 35, 40, 50, 60, 70, 90, 115, 120 and 140 HP listings.
The supplied data also specifically includes a 1996 Tohatsu 90 HP application.
The Nissan and Tohatsu application data spans multiple years, horsepower ranges and assemblies. Do not assume every engine of a listed horsepower uses this seal.
Verify the exact model, year and original drain-plug seal part number before ordering.
Pro Marine Aftermarket Version Available
Looking for an aftermarket alternative? Pro Marine also stocks the 9522P drain plug seal for customers who do not require the genuine Mercury-branded part.
This gives dealers, service shops and boat owners a choice between OEM Mercury 8M0082880 and the Pro Marine aftermarket 9522P.

Replace the Seal When Servicing Gear Lube
Mercury recommends replacing the seal when changing gear lubricant or whenever the existing seal shows signs of wear or damage.
During lower-unit service:
- Remove the applicable gearcase drain/fill screw.
- Remove and inspect the existing seal.
- Drain and refill the gearcase according to the engine manufacturer's procedure.
- Install the correct drain-plug seal.
- Reinstall and tighten the screw according to the manufacturer's specification.
- Inspect the area for leakage after service.
Why the Lower Unit Drain Plug Seal Matters
Outboard gearcases operate submerged in water. The drain and fill screws therefore need reliable seals.
A damaged or incorrectly installed seal can compromise the sealing point around the screw. Water contamination can reduce the lubricating ability of the gear oil and may contribute to internal gearcase damage.
If drained gear lube appears unusually milky or shows other signs of water contamination, the gearcase should be inspected rather than simply refilled and returned to service.

Prefer the OEM version? The 8402-1 non-oiling VRO fuel pump is also available for the same compatible Johnson / Evinrude application family.
What This Part is Used For
The fuel pump supplies gasoline from the boat's fuel system to the engine. The Pro Marine 8402-1P is specifically a non-oiling VRO configuration, so it is intended for applications where the pump provides fuel delivery without performing the oil-metering function.

Common Reasons for Replacement
- Hard starting or extended cranking
- Fuel starvation at higher RPM
- Loss of power under load
- Hesitation during acceleration
- Fuel leaking from the pump assembly
- Cracked or deteriorated pump housing
- Weak fuel delivery
- Replacement of an obsolete OEM pump number
Why Choose the Pro Marine 8402-1P?
