What to do if my Sea-Doo Boat engine does not turn over?
- B
  Brandi TorresAug 19, 2025
  If your Sea-Doo Boat engine won't turn over, first, ensure the safety lanyard cap is correctly installed over the post. Other potential causes include a burnt fuse (main, electric starter, MPEM, or EMS ECU), so check the wiring and replace any blown fuses. Battery connections may be corroded or loose, so try cleaning them. For other issues, such as the EMS ECU not recognizing the safety lanyard, a discharged battery, a water-flooded engine, a faulty sensor, or a seized engine or jet pump, it's best to consult an authorized Sea-Doo dealer.

  If your Sea-Doo Boat engine turns normally but doesn't start, begin by refilling the fuel tank, ensuring the fuel is not empty or water-contaminated. Replace any fouled or defective spark plugs. Also, try reconnecting the fuel pump connector. Check the wiring and replace any blown fuses. For issues like a fuel-flooded or water-flooded engine, or a faulty component in the engine management system, it's best to consult an authorized Sea-Doo dealer.

  Laura PerezAug 26, 2025
  If you get a long beep when installing the safety lanyard on your Sea-Doo Boat, try reinstalling the safety lanyard cap correctly over the post. Ensure you are using a safety lanyard that has been programmed for your watercraft. If the issue persists, try another programmed safety lanyard or clean the safety lanyard cap to remove any salt water. If none of these steps work, the DESS post may be defective, or there might be an issue with the EMS ECU or wiring harness, requiring you to consult an authorized Sea-Doo dealer.
