Product Details
This 100% new fuel injector is designed for selected Mercury and Mariner outboard applications, including 75–115 EFI 4-Stroke 1.7L engines and Mercury Verado 135–300 HP engines with L4 and L6 cylinder configurations.
It is sold as one individual fuel injector, not as a six-injector set. The injector is an aftermarket replacement and is supplied for comparison with the applicable Mercury reference numbers listed below.
- 100% new aftermarket fuel injector.
- Single injector assembly per order.
- Application coverage includes Mercury/Mariner 75–115 EFI and Verado 135–300 HP engines.
- Check the engine model, cylinder configuration, and serial-number range before ordering.
OEM Reference Numbers
The following Mercury reference numbers are associated with this replacement injector:
| Brand | Reference Number |
|---|---|
| Mercury | 8M0041571 |
| Mercury | 8M0006027 |
| Mercury | 892811T01 |
| Mercury | 8M0222278 |
| Mercury | 892811T02 |
Reference numbers are provided for identification and application comparison. They do not by themselves confirm fitment for every engine listed by a retailer.
Engine Compatibility
Use the complete engine model and serial number to confirm compatibility. Keep the horsepower, stroke, cylinder configuration, and serial range together when checking your application.
| Brand | Engine Family | Horsepower | Stroke / Configuration | Serial or Application Condition | Reference Number |
|---|---|---|---|---|---|
| Mercury / Mariner | EFI outboard | 75, 80, 90, 100, 115 HP | 4-Stroke EFI, 1.7L | SN 1B366823 to 2B094995 | 8M0041571 |
| Mercury / Mariner | EFI outboard | 75, 80, 90, 100, 115 HP | 4-Stroke EFI, 1.7L | SN 0P459572 to 2B094995 | 8M0041571 |
| Mercury | Verado | 135–300 HP | 4-Stroke, L4 or L6 cylinder | Verify the exact engine model and serial number | 8M0041571, 8M0006027, 892811T01, 8M0222278, 892811T02 |
Catalog references also identify 8M0041571 for selected 135–150 HP L4 Verado applications and 200–275 HP L6 Verado applications with specific serial ranges. Because Verado fitment varies by generation and serial number, compare the original injector and confirm the engine serial range before installation.

- Disconnect the injector electrical connector and fuel connections carefully. Catch and dispose of any released fuel safely.
- Remove the retaining hardware and carefully remove the original injector.
- Inspect the fuel rail, seals, and connector for damage or contamination. Lubricate replacement seals only as specified by the engine service manual.
- Install the new injector, secure the retaining hardware, and reconnect the fuel and electrical connections.
- Pressurize the fuel system and inspect all connections for leaks before starting the engine.
- Complete any required fuel-system checks or diagnostic procedures specified in the service manual.
Maintenance and FAQ
How can I tell whether a fuel injector may be failing?
Possible symptoms include rough idle, misfire, poor acceleration, hard starting, uneven running, or increased fuel consumption. These symptoms can have several causes, so test the fuel system and follow the engine manufacturer's diagnostic procedure before replacing an injector.
Is this an OEM injector?
No. This listing is for a 100% new aftermarket replacement injector. The Mercury reference numbers are supplied only to help compare the replacement with the original application.
Does one order include six injectors?
No. One order includes one individual fuel injector. Engines that use multiple injectors require the correct quantity for the specific engine.
Does it fit every Mercury or Mariner 75–115 HP engine?
No. The documented 75–115 HP applications are 4-Stroke EFI 1.7L engines within the specified serial-number ranges. Confirm your complete serial number and compare the original component before ordering.
Does it fit every Verado 135–300 HP engine?
The product is intended for Verado 135–300 HP L4 and L6 applications, but Verado fitment depends on the exact model generation and serial number. Verify those details before purchase.
Safety and Important Information
- Fuel-system service involves flammable fuel and should be performed in a well-ventilated area away from ignition sources.
- Always relieve fuel pressure and follow the applicable engine service manual.
- Do not install the injector if the connector, body, seals, or reference number differs from the original part without confirming compatibility.
- Professional installation is recommended when the correct fuel-system service procedure is unavailable.
