Changing Oils - Crusader 5.7L Carburetor Owner's Operation And Maintenance Manual

CHANGING OILS

WARNING
IMPORTANT: The Federal Water Pollution Control
Act prohibits the discharge of oil or oily waste into
or upon the navigable waters and continuous zone
of the United States, if such discharge causes a
fi lm or sheen upon, or discoloration of the surface
of the water, or causes sludge or emulsion beneath
the surface of the water. Violators are subject to a
penalty of $5,000.00.
Refer to the MAINTENANCE SCHEDULE for oil change
intervals. The engine and transmission oils should be
changed prior to placing the boat into storage.
The transmission oil change should be performed by an
authorized dealer, at specifi ed intervals.
IMPORTANT: Change the engine oil when the engine
is warm from operation. Warm oil fl ows more freely,
and allows more foreign material and impurities to be
removed.
1. With the engine at normal operating temperature,
remove the dipstick and install a crankcase oil
pump onto the dipstick tube (Figure 10-18).
Insert the discharge hose into a suitable
container. Pump the oil from the engine until the
crankcase is empty. Remove the oil pump from
the dipstick tube.
2. Remove the oil fi lter by turning it
counterclockwise, using an oil fi lter wrench if
necessary. Discard the old fi lter and sealing ring.

3. Coat the sealing ring, on the new fi lter, with a
light coating of clean engine oil. Install the oil
fi lter securely by hand. DO NOT overtighten.
4. Fill the engine with the recommended oil, see OIL
REQUIREMENTS, through the oil fi ll location on
the valve cover (Figure 10-19).

5. Start the engine and operate for 5 minutes to
circulate the oil throughout the engine. Check
entire system for leaks, especially around the oil
fi lter.
6. Stop the engine and wait 5 minutes to allow the
oil to completely drain down. Check the oil level
and add oil, if needed, to bring the engine oil to
the proper level.
