Installation Guide

  1. Shut off the engine and allow it to cool completely. Ensure the work area is well-ventilated.
  2. Turn off the boat's fuel supply valve to prevent fuel flow.
  3. Place a suitable catch pan or absorbent rags below the fuel filter housing to collect any spilled fuel.
  4. Locate the Gen III fuel cooler and identify the fuel filter housing.
  5. Carefully remove the housing cover or fasteners according to your engine's service manual.
  6. Remove the old filter disc. Take note of its orientation and any accompanying seals or O-rings.
  7. Clean the inside of the housing with a clean, lint-free cloth, ensuring no dirt or debris remains.
  8. Install the new filter disc in the correct orientation.
  9. Replace any seals or gaskets if they show signs of wear or damage.
  10. Securely reinstall the housing cover and tighten it to the manufacturer's specified torque.
  11. Turn the fuel supply back on and prime the fuel system if necessary.
  12. Start the engine and carefully inspect the filter housing for any signs of fuel leaks.

Troubleshooting & FAQ

Q: How do I know if this filter fits my engine?
A: This filter is specifically for MerCruiser sterndrive and inboard models from 2004 and newer that use the Gen III fuel cooler system. The most reliable way to confirm fitment is by matching your old filter's part number to 35-892665, 8M0204703, or Sierra 18-7715.

Q: What are the signs my fuel filter needs to be replaced?
A: Common symptoms of a clogged or failing fuel filter include engine hesitation, loss of power, sputtering at high speeds, stalling, or difficulty starting. Visible water or debris in the old filter is also a clear indicator for replacement.

Q: Why is it important to use a water-separating filter?
A: Water in the fuel can cause poor engine performance, corrosion of fuel system components, and significant engine damage. A water-separating filter is essential for removing emulsified water from gasoline, protecting your engine and ensuring reliability.

Q: How often should I replace my fuel filter?
A: It is generally recommended to replace your fuel filter annually or every 100 hours of engine operation, whichever comes first. Refer to your engine’s service manual for the specific maintenance interval recommended by Mercury.
