QUARTERLY MAINTENANCE
18-2
the throttle/shift control lever is in neutral. The en-
gine must be warm.
Step 2: Open the engine compartment and locate
the oil drain hose, which runs from the bottom of
the oil pan along the port side of the engine. At the
end of the oil drain hose is a brass plug.
Note: Never drain oil into the bilge or into the
water. Wipe up any spilled oil immediately, and
dispose of the rags and drained oil in a proper
manner on-shore.
Step 3: Remove the engine oil cap located on
the valve cover. This will speed-up the oil drain-
ing process.
Step 4: Remove the bilge drain plug to drop the
drain hose through the hole. Drain the oil into a
container on the ground. (On some v-drive models,
you will thread the line through a hole that runs through
the lower edge of the transom.)
Step 5: Loosen the brass end cap to allow the oil
to drain; be careful to avoid rounding off the edges
of the brass end cap.
Step 6: The oil filter should be changed each
time the oil is changed. Remove the oil filter and
dispose of it properly on-shore.
Step 7: Fill a new MasterCraft oil filter about half
full with clean engine oil. Lightly lubricate the oil
filter gasket and spin the filter on until the gasket
makes contact. Hand tighten the filter one-quarter
to one-half turn after contact. DO NOT use a filter
wrench to tighten.
Step 8: Re-attach the oil drain plug to the end of
the hose and refill the crankcase through the oil cap
opening on the valve cover. Check the oil level with
the dipstick. If this is the initial quarterly oil change,
re-attach a cable tie around the oil drain hose and
the water line on the port side of the engine as it
came from the factory, to keep the line from coming
in contact with any hot areas.
