Step-by-Step Instructions
1. Locate the Fuel Filter
The fuel filter is typically located near the carburetor or fuel pump on the engine. Consult your Yamaha 115 outboard service manual for the exact location.
2. Shut Off Fuel Supply
Before removing the old fuel filter, shut off the fuel supply by closing the fuel valve or pinching the fuel line.
3. Remove the Old Filter
Using a fuel filter wrench or your hands, carefully unscrew the old fuel filter from the fuel line. Be prepared for a small amount of fuel spillage.
4. Inspect the Old Filter
Examine the old fuel filter for any signs of contamination or debris. This can indicate a need for more frequent filter replacements.
5. Install the New Filter
Apply a small amount of clean engine oil to the O-rings on the new fuel filter. Screw the new filter onto the fuel line by hand, then tighten it using a fuel filter wrench or your hands.
