System Descriptions

RAW WATER COOLING SYSTEM

The Raw Water Pump (rear half of 15/1) draws outside raw water

from the sea cock and strainer and pushes it through a hose

(16/13), into the Heat Exchanger (16/1). As it passes through the

Heat Exchanger it absorbs heat from the fresh water coolant.

The raw water is then discharged into the Exhaust Elbow where it

is sprayed on the hot exhaust gases to cool them. It then flows

with the exhaust gas into the typical "wet marine" exhaust system.

CAUTION

Whenever the engine is cranked, the Raw Water Pump

continues to pump water through the raw water system.

With continued cranking, it is possible to fill the Exhaust

Percolating Muffler, the Exhaust Hose, the Exhaust Elbow,

and if the Exhaust Valve is open, the engine combustion

chamber, with raw water. If the raw water is sea water, the

damage to the engine can be severe. If this ever happens,

corrective action must be taken at once. If the engine will

not start within 7 to 10 seconds, stop cranking!
