Signs the Ignition Coil Needs Replacing

  • - Difficult Starting: Engine cranks but struggles to start.
  • - No Spark: One or both spark plugs fail to produce an ignition spark.
  • - Intermittent Misfiring: Engine runs unevenly or loses ignition intermittently.
  • - Poor Acceleration: Engine hesitates or lacks power under load.
  • - Engine Stalling: Motor unexpectedly stops, particularly when warm.
  • - Heat-Related Failure: Ignition performance deteriorates as the engine warms up.
  • - Damaged Ignition Leads: Cracked insulation, corrosion or damaged connections.
  • - Visible Coil Damage: Cracked casing, heat damage or corrosion.
  • These symptoms may also result from spark plugs, stop-switch wiring, CDI components or other ignition-system faults.

Important Fitment Information

  • - Confirm the engine model, serial number and original ignition coil number.
  • - This is a genuine Tohatsu OEM component, not an aftermarket replacement.
  • - Verify the correct coil for M25H/M30H versus MX25H/MX30H configurations.
  • - Compare ignition lead lengths, mounting points and electrical connectors.
  • - Check the spark plug caps and leads for corrosion or deterioration.
  • - Inspect the ignition system before replacing the coil to avoid unnecessary repairs.
  • - Disconnect the battery where fitted and follow the manufacturer's electrical safety procedures.
  • - Use the correct service-manual procedures for ignition system testing.
  • - Do not assume all 25HP and 30HP outboards use this assembly.
