  If your Sea-doo Boat engine turns over but doesn't start, several factors could be at play. Begin by checking for fault codes related to the fuel injection system. Ensure the engine isn't in drowned mode by releasing the throttle lever. Also, verify that the battery voltage is sufficient, and that there is adequate fuel pressure. Examine the fuel injectors to confirm they are functioning correctly and inspect the spark plugs for any issues, replacing them if needed. Additionally, check for water-contaminated fuel or a dirty fuel filter, addressing these issues by siphoning/refilling the fuel or cleaning/replacing the filter.

  The Sea-doo Boat engine might fail to turn over due to several reasons. It could be due to using the wrong safety lanyard; ensure you are using the programmed one. Other potential causes include a faulty or disconnected safety lanyard switch, a burnt fuse in the battery or starting system, a discharged battery, loose battery connections, poor ground contacts, or a seized jet pump. Also, check for a defective start/stop switch. Check and clean or tighten connections as necessary, and replace any burnt fuses after inspecting the wiring.

  A Sea-doo Boat engine might turn over slowly due to several reasons. Check for loose battery cable connections and ensure they are clean and tight. A discharged or weak battery could also be the culprit, so check, charge, or replace it as needed. Other potential causes include a restriction in the jet pump (check and clean it), or the outside temperature may be too low, causing the oil to be too thick. In this case, consider changing the oil viscosity or ensuring the battery capacity is sufficient for the cold temperature.
