  Jason ChavezAug 19, 2025
  If you're experiencing power loss with your Yamaha Outboard Motor, several factors could be responsible. Start by inspecting the propeller for damage and have it repaired or replaced if necessary. Check that the propeller's pitch and diameter are correct for optimal speed. Adjust the trim angle for efficient operation. Ensure that the boat bottom is clean from marine growth, and the gear housing isn't tangled with weeds or other foreign matter. Inspect the spark plugs, replacing them if they are fouled or incorrect. Also, make sure that you are using the specified engine oil. Check the fuel lines and filter for obstructions or clogs, and use clean, fresh fuel.

  If your Yamaha Outboard Motor idles irregularly or stalls, there are several potential causes to investigate. Begin by checking the spark plugs; if they are fouled or the incorrect type, clean or replace them. Inspect the fuel system for any obstructions, such as pinched or kinked fuel lines. Ensure that you're using clean, fresh fuel. Clean or replace the fuel filter if it's clogged. Also, make sure that the air vent screw on the fuel tank is open and the choke knob is in home position. If applicable, ensure the fuel joint connection is correct and the battery lead is securely connected. Check that the motor angle is at normal operating position.
