Important: Engines require air to operate. For this reason, do
not operate the engine or generator with this area obstructed.
Important: The engine manual supplied by the manufac-
turer includes complete and detailed information about oper-
ating and maintaining your boat’s engines. Be sure to read
it. Do not start or operate the boat’s engines until you
have done so. The life and performance you receive from
your engines depends greatly on the way you care for it.

Important: The Hour meter will run if you leave the ignition
switch on when the engine is not running. This unnecessarily
increases the number of engine hours.
Note: Instruments have a tolerance for accuracy. In addition,
each engine may operate at differing values at the same RPM.
As long as the instruments are reading within the proper operat-
ing range, the engine is operating properly.
