Why does my Yamaha FX High Output WaveRunner 2007 engine run irregularly or stall?

If your Yamaha Boat's engine runs irregularly or stalls, several factors could be responsible. It might simply be low on fuel, so refill it as soon as possible. The fuel could also be stale or contaminated, or there might be an issue with the fuel tank itself, in which case you should have it serviced by a Yamaha dealer. Other potential causes include a faulty spark plug (replace or adjust the gap), a disconnected or damaged spark plug cap (connect properly or replace), or issues with the electrical wiring (tighten or connect properly). For fuel injection system problems, have it serviced by a Yamaha dealer.
