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 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 engines should be flushed after

each use. Refer to the engine owner’s manual for the proper engine flushing

procedure.

1.5 Propellers

The propellers convert the engine’s power into thrust. They 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

SERIOUS INJURY TO PASSENGERS AND DAMAGE TO THE MOTOR OR BOAT. IF YOUR

BOAT RUNS AGROUND, EVALUATE THE DAMAGE THEN PROCEED AT LOW SPEED

TO THE NEAREST SERVICE FACILITY AND HAVE AN IMMEDIATE INSPECTION MADE

BEFORE FURTHER 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

INSPECT THE BILGE AREA FOR LEAKS SO THAT THE BOAT DOES NOT SINK WHILE

MOORED.
