6.9) Exhaust System:
In the Perkins engine, a water pump draws water through the intake port, circulates it through a heat
exchanger, where it is pumped in the muffler and overboard through the exhaust port. The salt water in
the heat exchanger lowers the temperature of the engine coolant circulated through the engine block by
means of the normal engine water pump. This coolant is 50% ethylene glycol (anti-freeze) and 50%
fresh water and protects the system to approximately -34
0
F
The ethylene glycol should be used at all times to help prevent corrosion in the engine.
7. ENGINE CONTROLS
7 .1) Description:
The engine controls for your boat consist of throttle and gear shift levers mounted on the starboard and
port side of the steering pedestal, respectively. The instrument panel is located in the inside port
cockpit coaming.
The instrument panel on the 40 consists of a combination keyed ignition switch and start switch, a
toggle switch for panel lights, a momentary push button for engine stop, gauges for amperage, cooling
water temperature and oil pressure, an audio/visual warning device that lights and sounds for low oil
pressure or high water temperature, plus an electric tachometer for engine RPM.
The 40’s blower is activated from the master electrical panel below. It is recommended that your
blower be operated continuously during engine operation to circulate fresh air to the engine. it is not
necessary, however, to run the blower prior to starting as diesel fuel vapors do not pose an explosion
hazard.
