  1. Relieve the fuel pressure. Refer to Fuel Pressure Relief .
  2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
  3. Ensure that the fuel level in the tank is less than 1/4 full. If necessary, drain the fuel tank to at least this level. Refer to Fuel Tank Draining .
  4. Remove the exhaust muffler assembly. Refer to Front Pipe Replacement : LNQ  → LF1  → LE5 .
  5. Remove the propeller shaft, if equipped. Refer to Propeller Shaft Replacement .
