2270 CENTER CONSOLE
1.4 Engine Cooling System
Outboard engines are raw water (sea water) cooled. Water is pumped through the water inlets,
circulated through the engine block, and relinquished with the exhaust gases through the propeller
hub. The water pump uses a small impeller made of synthetic rubber. The impeller and water pump
cannot run dry for more than a few seconds. In most outboard motors, some cooling water is
diverted through small ports below the engine cowling. This allows the operator to visually check
the operation of the cooling system. When the engine is started, always check for a steady stream
of water coming out of those ports.
NEVER RUN AN OUTBOARD MOTOR WITHOUT WATER FLOWING TO THE WATER
PUMP. SERIOUS DAMAGE TO THE WATER IMPELLER OR ENGINE COULD RESULT.
Note: If the boat is used in salt or badly polluted water, the engine should be flushed after
each use. Refer to the engine owner’s manual for the proper engine flushing pro-
cedure.
1.5 Propeller
The propeller converts the engine’s power into thrust. Propellers come in a variety of styles,
diameters and pitches. The one that will best suit the needs of your Pursuit will depend somewhat
on your application and expected average load. Propeller sizes are identified by two numbers
stamped on the prop in sequence. The 1st number in the sequence (example 14 x 21) is the diameter
of the propeller and the 2nd number is the pitch. Pitch is the theoretical distance traveled by the
propeller in each revolution. Always repair or replace a propeller immediately if it has been
damaged. A damaged and therefore out of balance propeller can cause vibration that can be felt
in the boat and could damage the engine gear assembly. Refer to the engine owner’s manual for
information on propeller removal and installation.
RUNNING AGROUND OR STRIKING AN UNDERWATER OBSTRUCTION CAN RESULT IN SE-
RIOUS INJURY AND DAMAGE TO THE MOTOR OR BOAT. IF YOUR BOAT RUNS
AGROUND, EVALUATE THE DAMAGE THEN PROCEED AT LOW SPEED TO THE NEAR-
EST SERVICE FACILITY AND HAVE AN IMMEDIATE INSPECTION MADE BEFORE FUR-
THER USE OF THE CRAFT. A DAMAGED BOAT CAN TAKE ON WATER. KEEP ALL
LIFE SAVING DEVICES CLOSE AT HAND WHILE DRIVING TO A DOCK AREA. IF THE
BOAT CANNOT BE IMMEDIATELY REMOVED FROM THE WATER, THOROUGHLY IN-
SPECT THE BILGE AREA FOR LEAKS SO THAT THE BOAT DOES NOT SINK WHILE
MOORED.
