Check the Transmission Fluid Level
Because you will get an accurate reading only after the
engine has run long enough to thoroughly warm up, this should
be one of the last checks you conduct before boating. Run the
engine in the water at least fi ve minutes, and check the fl uid im-
mediately after shutting down to get an accurate reading.
Step 1:
After operating the engine at idle while in the water for
at least fi ve minutes or until warm, turn the engine OFF
and disconnect the engine safety starting switch. Be
sure the throttle/shift control lever is in neutral. Open
the engine compartment and locate the transmission
dipstick.
Note: The transmission fl uid level must be
checked immediately after the engine shut-down to
2007 MasterCraft Owners Manual - Page 15-8
prevent an incorrect reading. Fluid drains back into the transmission from the cooler and cooler
lines, and the dipstick could give a false reading if not done quickly.
Step 2:
Remove the dipstick and wipe it off with a clean rag. Quickly re-insert it fully and immediately remove. Check
that the level is at the FULL WARM mark on the stick.
Step 3:
Add or remove fl uid as necessary to maintain the level at the mark. It is as important to avoid overfi lling the
transmission fl uid as it is to avoid underfi lling. Use only the recommended automotive-type transmission fl uid.
Check with your MasterCraft dealer for the specifi cations. Never mix different types or brands of fl uid! The
manufacturer specifi es Dextron-III fl uid in the direct drive 1:1 transmission and 15W40 motor oil in the V-drives
and gear-reduction transmissions.
Quarterly (Every 50 Hours)
MasterCraft recommends that your quarterly—or 50 hour—maintenance
requirements be performed by your MasterCraft dealer. The staff there has the
proper equipment and technical training to best meet your service needs.
Lubricate the Engine Starter Gear and Shaft
Because this process should be completed while the en-
gine is cool and cannot cause burns to your skin, we recommend
you do this before starting the boat.
Step 1:
Ensure the engine is OFF and the engine safety starting
switch is disconnected. Be certain that the throttle/shift
control lever is in neutral. The engine must be cool.
Step 2:
Disconnect the positive (+) battery terminal.
Step 3:
Open the engine cover and locate the starter on the low-
er starboard side of the engine.
Step 4:
Disconnect the starter and carefully remove it.
Step 5:
Lubricate the starter bendix with a light coating of water-
proof grease or white lithium grease.
