1.3 Engine Lubrication
2-cycle outboard motors are lubricated by a variable ratio oil injection system. The oil tanks are
mounted below the stern bait station near the transom. Always monitor the oil level before each
cruise by checking the gauge in the helm or visually checking the oil level using the reference marks
on the tanks. When additional oil is needed, use only the type of oil specified by the engine
manufacturer. Refer to the engine owner’s manual for oil specifications and additional information
on the oil injection system.
4-cycle outboard engines have an oil sump in the crankcase that must be kept full of the type and
grade of oil recommended by the engine manufacturer. It is normal for 4-cycle engines to consume
a small amount of oil. Therefore, the oil must be checked before each use and changed at regular
intervals as instructed by the engine owner's manual. As with 2-cycle engines, use only the type
of oil specified by the engine manufacturer.
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
