Installation Notes

  1. Safety First: Disconnect the battery and relieve fuel system pressure according to your engine's service manual.
  2. Access Injectors: Remove any components blocking access to the fuel rail, such as the plenum or intake manifold cover.
  3. Disconnect: Carefully unplug the electrical connector from each injector you are replacing.
  4. Remove Fuel Rail: Unbolt the fuel rail from the intake manifold. Do not pry; lift it gently and evenly to pull the injectors out of their ports.
  5. Swap Injectors: Remove the retaining clip and pull the old injector from the fuel rail. Lubricate the new injector's O-rings with clean engine oil and press it firmly into the rail. Secure with the new clip.
  6. Reinstallation: Seat the fuel rail with the new injectors back into the intake manifold. Torque the bolts to the manufacturer's specification.
  7. Final Connections: Reconnect the electrical connectors and fuel lines. Reinstall any other components that were removed.
  8. Check for Leaks: Reconnect the battery. Turn the key to the "On" position (without starting the engine) to pressurize the system. Carefully inspect for any fuel leaks before starting the engine.

Troubleshooting & FAQ

How do I confirm this injector fits my engine?

The best way is to match your original part number to one of the direct replacements listed: Mercruiser 885176, Bosch 0280156081, GM 12567905, or Indmar 636051. You can also use the compatibility table and verify your engine model, year, and serial number range.

What are the signs of a failing fuel injector?

Common symptoms include rough idling, engine misfires (which may trigger a check engine light), poor acceleration, increased fuel consumption, and difficulty starting the engine. A fuel smell may also indicate a leak from a cracked or poorly sealed injector.

Is this a direct replacement for the Bosch 0280156081?

Yes, this injector is designed as a direct, aftermarket replacement for the Bosch 0280156081 and flows at the same rate, ensuring compatibility with your engine's computer.

What is the spray pattern and why does it matter?

This injector features a 4-hole spray pattern with a 30° dispersion angle. This design provides better fuel atomization compared to older single-hole pintle-style injectors, resulting in more efficient combustion, improved throttle response, and potentially better fuel economy.

How often should fuel injectors be replaced?

There is no fixed replacement interval for fuel injectors. They are typically replaced only when they fail or become clogged in a way that professional cleaning cannot resolve. Regular use of quality marine-grade fuel helps prolong their lifespan.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.

Safety & Important Info

  • Verify images/specifications vs your original part. If anything differs—even if your model appears compatible—do not purchase.
