What to do if SeaDoo 3D Boat engine turns over but doesn't start?
- LLinda McculloughJul 26, 2025
If your SeaDoo Boat engine turns over but doesn't start, there could be several reasons. For RFI models, a faulty component in the fuel injection system might be the cause, so check for fault codes. Ensure the engine isn't in drowned mode by releasing the throttle lever (RFI models). Other possible causes include low battery voltage (recharge or replace the battery), low or no fuel pressure (RFI models, check fuel pump pressure, fuse, and wiring), fuel injectors not working (RFI models, check injector operation and ECM output), no spark at the spark plug (check and replace spark plugs), a defective MPEM or ECM (check ignition system and replace if needed), or inverted spark plug cables (RFI models, reposition them correctly).
