Spark Plugs
A spark plug with cracked porcelain or damaged
threads should be changed immediately. If the
electrodes are badly worn or burned the plug should
also be replaced.
NOTE: Refer to the specifications section beginning
on page 102 for the recommended spark plug
type for your watercraft.
If the spark plug is in good condition, clean it with a
clean shop cloth and/or wire brush. Adjust the gap to
the recommended dimension of .028-.031 in. (0.7-0.8
mm) using a wire thickness gauge.
WARNING
Removing a spark plug while the engine or
exhaust system is hot could result in serious
burns. Wait until the engine has cooled or wear
protective gloves while servicing a spark plug.
