Spark Plugs - TOHATSU BFT 75A Owner's Manual

Spark Plugs

To ensure proper engine operation,
the spark plug must be properly
gapped and free of deposits.
The spark plug becomes very hot
during operation and will remain
hot for a while after stopping the
engine. Allow the engine to cool
before servicing the spark plug.
See page 127 for instructions of
handling the iridium spark plugs
(optional parts).
