Spark Plugs
The spark plugs are components that help make
ignition occur. As electrical potential builds on one
side of the gap based upon the energy distributed
by the ignition system, the potential eventually
grows large enough to cause the electric current
to jump the gap on the spark plug. This spark
is what ignites the compressed fuel generating
a controlled explosion that will power the piston
down and deliver power to the drive shaft.
Alternator
Under normal circumstances, the starter battery
would wear down after being used so often to
generate a spark for the engine. This isn't an
ideal setup because a strong battery is needed
for continual operation. A weak battery does no
good out on the water. The alternator recharges
the battery(ies) while the engine is running.
However, in an effort to conserve battery life, the
battery switch should still be turned off after every
trip and turned on at the start of every trip. This
limits the drain on the battery during non-use.
As optional equipment a 10 amp battery
charging system charges batteries when the
shore cord is connected to the vessel 3 prong
grounded plug which must be connected to a
GFCI outlet. Read and understand the following
label!
CAUTION
THIS VESSEL IS NOT EQUIPPED WITH A
GALVANIC ISOLATOR. USING THE BATTERY
CHARGER WHILE THE BOAT IS IN WATER
MAY CAUSE DAMAGE TO THE BOAT'S
ANODES AND/OR DRIVE SYSTEM.
Fuses
Your engine also comes equipped with fuses that
will burn out or "blow" when engine components
attempt to draw more power than the piece of
equipment or wiring can handle. When the fuse
blows, it breaks the circuit, and electricity stops
flowing. Before replacing the fuse, investigate the
cause of the problem, and why the equipment was
overworked. Your engine uses a helm mounted
fuse box which is accessible by lifting the starboard
bow backrest while other engines feature in-line
fuses, while still others feature a mixture of both.
Refer to your engine owner's manual for complete
details on your electrical system and the location
of any engine mounted over current protection.
Engine Exhaust System
Your engine expels the by-products of the engine
operation through an exhaust system, just like
automobiles do. In boats however, this exhaust
system mixes the debris left over after the power
stroke of the engine with the hot water that is
expelled after cooling the engine.
Basically the exhaust flows through the engine
before expelling the exhaust through the vertical
drive housing either just above the propeller, or
through the prop shaft.
Engine Fuel System
Refer to the system chapter of this manual for fuel
system specifics. Be sure to read and understand
the following warnings.
