Run these six checks before every session. If the board won't start or is behaving oddly, they're also the first six things to rule out.

The six checks

  1. 0:19 · Fuel — there's fuel in the tank and the fuel line is connected. See Fuel tank removal & installation.
  2. 0:26 · Sensor — the sensor is connected. (Applies to all 2018 and 2019 DFI and EFI models.)
  3. 0:40 · Spark plug — connected correctly and in good condition. See Spark plug check & replacement.
  4. 0:48 · Starter — working. Put the magnet into the light/start point to activate the starter and listen that it turns. See Starter removal & installation.
  5. 1:03 · Charge — the board is charged and ready. See Charging a petrol board.
  6. 1:12 · Freewheel test — turn it clockwise: it should engage and you hear the piston moving up and down. Turn it counter-clockwise: it should spin free — no engagement, no sound. See Freewheel removal & installation.
Tip: the freewheel test tells you two things at once — that the freewheel clutch is working (free one way, locked the other) and that the engine has compression (you feel and hear the piston on the clockwise turn).
Caution: if the freewheel is engaged in both directions, or spins free in both, stop — don't try to start the engine. That's a drivetrain fault to diagnose on the bench, not on the water.
Keep riding
