Step 6:
Return the starter to the engine and reconnect. After closing the engine compartment, reconnect the positive
(+) battery terminal.
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 (approxi-
mately three minutes in most applications), before changing the oil. Do not
run your engine without it being in water, unless you have the appropri-
ate 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 wa-
ter. 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-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.
Step 6:
The oil fi lter should be changed each time the oil is changed.
Remove the oil fi lter and dispose of it properly on-shore.
Step 7:
Fill a new MasterCraft oil fi lter about half full with clean engine oil.
Lightly lubricate the oil fi lter gasket and spin the fi lter on until the
gasket makes contact. Hand tighten the fi lter one-quarter to one-
half turn after contact.
DO NOT
use a fi lter wrench to tighten.
Step 8:
Re-attach the oil drain plug to the end of the hose and refi ll 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 fac-
tory, to keep the line from coming in contact with any hot areas.
