What does it mean when my SeaDoo 2002 GTX 4-TEC Boat beeps every 15 minutes?
A 2-second beep every 15 minutes on your SeaDoo Boat can indicate several issues: the watercraft is upside down, or there's a malfunction with the engine coolant temperature sensor, exhaust temperature sensor, engine oil pressure sensor, low pressure in the oil separator tank (engine oil leak), TOPS sensor, TOPS valve solenoid, engine ECU failure, bilge pump circuit (if equipped), or starter solenoid circuit. Turn the watercraft upright to resolve the first potential issue.
What causes lean fuel mixture in SeaDoo Boat?
A lean fuel mixture in your SeaDoo Boat can be caused by a low fuel level, stale fuel, or water-contaminated fuel. It can also be caused by clogged injectors or a defective sensor or engine ECU. Siphon and/or refill the fuel tank to resolve this issue.

If the SeaDoo Boat engine doesn't turn over, several issues could be the cause. Ensure the safety lanyard is correctly installed over the post. Other potential causes include a burnt fuse (main, electric starter, MPEM, or engine ECU), a discharged battery, corroded or loose battery connections, or a water-flooded engine. It could also be due to a faulty sensor, MPEM, or engine ECU, or a seized engine or jet pump. For burnt fuses, check the wiring and replace the fuse(s). For a seized jet pump, attempt to clean it; otherwise, further assistance from a Sea-Doo dealer may be needed.
