MAINTENANCE
CHANGE THE ENGINE OIL AND FILTER
e following service must be performed while the engine and boat are out
of the water. However, in order to thoroughly and properly drain all the
old oil, the boat engine needs to reach at least 140°F (60°C) rst. Since the
engine must be supplied with water to function, it is recommended to run
the engine while the boat is in a body of water, then promptly remove the
boat from the water and immediately perform the service. If you cannot
place the boat in a body of water or do not have access to a professional o-
shore hook-up to protect the engine and drive train components (as some
dealerships do), have a certied Ilmor dealer perform this service
A list of recommended oil for use in each MV8 engine can be found in
Engine Specications on page 11-1.
In areas where these recommended oils are not available, please contact
your local authorized service center for appropriate equivalents. Use of
supplemental oil additives is not recommended.
1. Ensure the engine is OFF and the engine safety starting switch is
disconnected. Leave the throttle/shi control lever in neutral. e
engine must be warm.
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. Many bodies of water are environmentally protected by law. Dumping
in the water can result in signicant nes.
3. Remove the engine oil cap located on the oil ll neck. (is access to air
will speed up the oil draining process.)
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.) Alternatively, a suction pump can be
hooked up to the oil drain hose to remove the engine oil.
5. Loosen the brass end cap at the end of the drain hose to allow the oil to
drain. Be careful to avoid rounding o the edges of the brass end cap
during loosening and tightening.
6. e oil lter is located at the rear of the engine. Remove the oil lter
and dispose of it properly on-shore.
7. Lightly lubricate the oil lter gasket and spin the new lter on until the
gasket makes contact. Hand-tighten the lter three-quarter to one turn
aer contact. DO NOT use a lter wrench to tighten.
