MAINTENANCE
Selecting Engine Oil
The engine crankcase oil should be selected to give the best performance in
your climate and operating conditions. During the hot summer months, use an
oil that has adequate lubrication under high operation temperatures. In cooler
weather, use an oil that will allow easy starting at the lowest temperature you
are likely to encounter. Make note of this when you are changing oil so you
select the right oil for your conditions.
We recommend SAE 40W40 of any good grade automotive oil of correct
viscosity which has an A.P.I. classification of “SH” for use in all PCM engines.
Multiple viscosity oils such as 20W40 and 20W50 which meet the A.P.I.
classification “SH” can be used during cold weather operation. Use the
following air temperature guidelines:
Above 50 degrees F........40W40
32 - 50 degrees F............30W30
Below 32 degrees F........20W50
Engine oil and filter must be changed after the 25 hour break-in period. After
this initial oil change, you should change the oil after every fifty hours of
operation.
Changing the Engine Oil
These instructions are for changing the oil while the boat is on a trailer.
CAUTION: All engine waste fluids are considered to be hazardous wastes.
Be certain these waste fluids are properly and legally disposed of in order
to avoid polluting and or possible citation by the authorities.
CAUTION: Do not operate the engine without cooling water flowing
through the water pump or the neoprene water pump impeller will be
damaged. The best way to insure adequate water flow when the boat is out
of the water is to install a Correct Craft Water Flush. Be aware that some
methods of providing water to the engine can allow water to be injested
into the combustion chamber; possibly resulting in severe engine damage.
Allow the engine to warm up to operating temperature by running it
slowly at idle speed. Watch the water temperature gauge to prevent
overheating.
Never start the engine with the engine box open
