How to fix a Sea-doo GTI 2003 with a rich fuel mixture?
If your Sea-Doo Boat has a rich fuel mixture (high fuel consumption), clean or replace the flame arrester if it is dirty or clogged.
Why does my Sea-doo GTI 2003 beep every minute?
If you hear a 2-second beep every minute on your Sea-Doo Boat (DI models), it indicates that the fuel tank level is low. Refill as soon as possible. Alternatively, it could indicate very low battery voltage, a malfunction of the coolant and exhaust gas temperature sensors, TPS (throttle position sensor), CPS (crankshaft position sensor), or an MPEM malfunction. For these issues, refer to an authorized SEA-DOO dealer.
How to fix a Sea-doo GTI 2003 when the engine does not turn over?
If your Sea-doo Boat engine does not turn over, install the safety lanyard cap over the post. Also, check the wiring and replace any burnt fuses on the MPEM or in the rear electrical box related to the battery, starting system, or fuel pump (DI models).
How to resolve cavitation issues in my Sea-doo Boat?
If your Sea-Doo Boat is experiencing cavitation, it could be due to a clogged jet pump water intake. Clean it to resolve the issue. Another cause may be weeds or debris jammed around the impeller, so clean it and check for damage. It may also be due to a damaged impeller, which would need to be replaced. If you are using a safety lanyard that purposely does not allow the watercraft to reach top speed (DI models), use a safety lanyard that allows you to reach top speed. Alternatively, the monitoring system may have put the watercraft in limp home mode due to a component malfunction (DI models); release the throttle so that the engine returns to idle speed.
What to do if the monitoring beeper sounds continuously on my Sea-doo Boat?
If the monitoring beeper on your Sea-Doo Boat sounds continuously, it may be due to a clogged jet pump water intake, which requires cleaning. Alternatively, the coolant system might be clogged, necessitating a flush.
Why does my Sea-doo GTI 2003 beep twice when installing the lanyard?
If you hear 2 short beeps while installing the safety lanyard on the post of your Sea-Doo Boat, it means the engine can be started. If the beeps persist, reinstall the safety lanyard cap correctly over the post, use a safety lanyard that has been programmed for the watercraft, try another programmed safety lanyard, or clean the safety lanyard cap to remove salt water. If the problem persists, refer to an authorized SEA-DOO dealer.
How to troubleshoot a Sea-doo GTI 2003 engine that turns slowly?
If the Sea-Doo Boat engine turns slowly, check, clean, and tighten any loose battery cable connections.
What does a beep every 15 minutes mean on my Sea-doo Boat?
If you hear a 2 seconds beep every 15 minutes on your Sea-Doo Boat (DI models), it indicates that the oil injection reservoir level is low. Refill it.
Why won't my Sea-doo Boat run above idle speed?
If your Sea-Doo Boat engine cannot run above idle speed, try removing and reinstalling the safety lanyard on its post. This issue could be due to the monitoring system putting the watercraft in limp home mode because of a component malfunction (DI models).
Why is my Sea-doo GTI 2003 pulling to one side?
If you notice your Sea-Doo Boat pulling to one side, refer to an authorized SEA-DOO dealer, as this may indicate that one side vane is not functioning correctly while the watercraft is at speed.
