Flooded Engine - ProBoat Rockstar 48 Owner's Manual

Spark Plug Test
CAUTION: Before testing the spark plug, clean up
spilled fuel and close fuel containers. Failure to do
can result in injury, fire or damage.
Remove the spark plug from the engine and attach the
plug wire and boot to the spark plug. Place the threaded
end of the spark plug against the muffler. Press the Bind/
R.O.S.S button to turn over the engine and ensure there
is a spark.
If there is no spark:
• Adjust the spark plug gap to 0.6–0.7mm (0.24–0.27 in)
• Install a new spark plug (LOSR5017)
CAUTION: Do not test the spark plug near the
spark plug hole or residual fuel may ignite.
