Systems, Controls & Indicators
Exhaust
The engine exhaust system removes the gases produced by the running
engine and helps to vent them away from the boat. Inboard engines are
equipped with a muffler and may use water injection as part of the exhaust
system. Some stern drives are equipped with an exhaust diverter valve
which, when activated, routes engine exhaust to through-transom exhaust
pipes or down through the propeller hub. Through-transom exhaust is only
used when well offshore. Never change or modify the standard
manufactured exhaust system.
Cooling
The majority of marine engines are cooled by the continuous intake of raw
lake water and circulating it around components. Inboards are equipped
with seacocks and strainers at the raw water intake. Some marine engines
used in saltwater may be equipped with a self-contained freshwater cooling
system that pumps engine coolant through a heat exchanger to reduce
engine temperature. Raw water is circulated through the other side of the
heat exchanger to absorb engine heat from the
coolant.
Any water intake or outlet below the water line is
equipped with a seacock. Seacocks, located at
the through-hull fitting, should be kept closed
during long periods of inactivity and opened only
when needed.
Keep seacocks closed during periods of inactivity. A
downstream hose failure could flood the boat if the seacock is
left open.
Electrical
The boat is equipped with a 12-volt direct current (12 VDC) negative ground
electrical system. The positive (red) wire is hot and feeds current from the
battery to the electrical systems. The negative (black) wire is ground and
completes the circuit back to the battery. Until the engine is running at high
idle or faster, all electrical power comes from the main battery. Once the
engine is started and running above 1200 RPM, electrical power is then
provided by the engine alternator. The alternator provides more power as
engine speed is increased. When the engine is operating, the alternator is
charging the battery.
