  If your Sea-doo Boat engine won't start, there are several potential causes: * The safety lanyard may be incorrect; use the one programmed for your watercraft. * A burnt fuse on the MPEM or in the electrical box (battery, starting system, or fuel pump on fuel injection models) could be the issue; check the wiring and replace the fuse. * The battery may be discharged or disconnected; check and recharge it. * Battery connections might be poor; check, clean, and tighten them. * There may be poor or corroded ground contacts (engine, starter, etc.); check, clean, and repair them.
