Transmission/V-Drive System - Malibu Boats Wakesetter 20VTX 2019 Owner's Manual

5. Some small amount of residual used oil may be inside the filter.
Keep a shop rag or similar catch under the filter as it is removed from
the boat.
6. Some mechanics choose to cut apart an oil filter to examine for
any evidence of metal shavings or other unwanted signs of engine
wear. If you choose to do so, be sure to cut over a container. Clean
up any oil that ends up spilled.
7. Also examine the o-ring. If it sticks to the filter base, it should be
replaced.
8. Pour a SMALL amount inside the replacement oil filter. Using
your hand or a small, clean brush, spread the oil around the interior
of the oil filter.
9. Using the oil filter tool, secure the oil filter in place on the engine.
Tighten securely by hand, but do not force the filter as it may crush or
break the seal if over-tightened.
Adding New Oil:
1. Replace the drain line cap on the drain line and thread the drain
line back to adjacent to the oil pan.
2. Remove the oil fill cap on top of the valve cover.
3. Place a clean funnel within the oil fill cap.
4. Pour the approximately eight (8) quarts of oil in the engine
through the funnel, allowing time for the fill to occur. As you approach
the eighth (8th) quart, slow down (it takes a little time for the oil to
move through the oil system) and start watching the fill line on the
dipstick. (Always clean the dipstick between readings to ensure
accuracy.)

5. Stop filling oil into the system when you reach the FULL mark
on the dipstick, regardless of how much oil has been added. OVER-
FILLING CAN DAMAGE THE SYSTEM!
NEVER REUSE OIL! Only new 5W30
SYNTHETIC oil should be added to the oil
system!

Transmission/V-Drive System

Transmission fluid checks must be done ONLY when the
transmission fluid is heated. Therefore, the boat should be run in a
body of water for at least five (5) minutes, and then shut down.
1. Remove and wipe down the transmission dipstick.
2. Reinsert, BUT DO NOT SCREW DOWN FLUSH WITH THE
HOUSING (you will get an erroneous reading). Check the level.
3. Transmissions should register 2.5 quarts of ATF fluid.
4. V-drive boats: remove and wipe down the V-drive dipstick.
5. V-drives should have one-and-a-quarter (1.25) quarts of Mobil
SHC 630 Gear and Bearing Oil.
