However, in an e ort to conserve battery life, the starter battery
should still be turned o a er every trip. is limits the drain on
the battery while the boat is not in use. e alternator will only
recharge the battery while the engine is running. So if the battery is
drained before it can provide the initial spark to the engine to start
the serpentine belt turning, the alternator cannot charge the battery
system.
Fuses
In addition, the engine comes equipped with fuses that could
“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 owing. Before
replacing the fuse, investigate the cause of the problem, and why the
equipment was overworked. Some engines feature a fuse box, while
others 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.
ENGINE EXHAUST SYSTEM
Your engine expels the by-products of the engine operation through
an exhaust system, just like cars do. In boats however, this exhaust
system mixes the debris le over a er the power stroke of the engine
with the hot water that is expelled a er cooling the engine. Basically
the exhaust system contains the exhaust manifolds, exhaust vent and
most likely a catalytic converter. Basically the exhaust ows through
the catalytic converter to purify the exhaust before expelling the
exhaust through the stern drive either just above the propeller, or
through the prop sha .
