MasterCraft recommends that your quarterly–or 50-hour–maintenance requirements be per-
formed by your MasterCraft dealer. The staff there has the proper equipment and technical train-
ing to best meet your service needs.
CHANGE THE ENGINE OIL
In order to thoroughly drain all the old oil,
you will need to run the boat engine long
enough to reach at least 140 degrees F
(approximately three minutes in most applica-
tions), before changing the oil. Do not run your
engine without it being in water, unless you
have the appropriate, professional hook-up
available to protect the engine and drive-train
components. If this is not available to you, have
your MasterCraft service technician perform
this service.
Step 1: Ensure the engine is OFF and the
engine safety starting switch disconnected. Be
certain that the throttle/shift control lever is in
neutral. The engine 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 immedi-
ately, 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
draining 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.
