148 Care & Maintenance | 2021 OWNER’S MANUAL
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 OIL SHOULD BE USED AS
OUTLINED ABOVE.
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 as this will cause an erroneous reading. Check
the level.
3. Transmissions should register approximately two-and-a-
half (2.5) quarts of Automatic Transmission Fluid.
4. V-drive boats: Remove the stick, wipe down, reinsert
unseated. Remove and check the level.
5. V-drives should have one-and-a-quarter (1.25) quarts of
Mobil SHC 630 Gear and Bearing Oil .
6. If the ATF fluid and Mobil SHC 630 Gear and Bearing
Oil appear clear, add the specified fluid only to the full
line. DO NOT add any fluid other than the specified
fluid as it can damage the system and void the warranty.
OVERFILLING CAN DAMAGE THE SYSTEM .
7. Even if the fluids appear clear, replace transmission fluid
annually, and V-drive fluids every 1200 hours or every
three (3) years, whichever occurs first.
Fuel System
This is important. Debris and water may enter the fuel
system, even with the careful protection built into the system.
Periodic replacement of the fuel filter is required to protect the
fuel pump and provide the proper fuel pressure to the engine.
Due to the need to use only specialized tools that are not
available to the public, and because the fuel lines are pressurized,
no fuel system maintenance can be completed by a consumer.
One fuel filter is located within the fuel tank, while another is
on the engine. Even though it is more accessible, because it
is under pressure this also is restricted to replacement by an
authorized Malibu dealer.
While some boat owners may not have a dealer close at
hand, this maintenance needs to be completed ONLY by trained
technicians with the appropriate, specialized tools. We apologize
for any inconvenience.
An annual replacement is recommended for both filters.
Hydraulic Steering System
The steering in Malibu boats features a hydraulic system
that can be maintained or repaired only with specialized tools.
Because of the potential for physical harm when working on
this system, it cannot be checked, changed or repaired by
consumers. Only an authorized Malibu dealer has access to the
tools and system.
Check the Safety Equipment
If you have not done so previously, check the fire
extinguishers and personal flotation devices. Check the
condition of (and replace as necessary) drain plugs, bilge pumps,
and exhaust flaps. Repair or replace anything that appears
damaged or incapable of performing its function.
Power Wedge III and Surf Gate Manual
Extension and Retraction
For boats equipped with these features, it is important for
the authorized Malibu dealer to verify the manual extension and
retraction function is operational, in case the consumer ever
has to perform this due to the failure of the automated system
controlled through the video screen.
For the Power Wedge III, using a small (stubby) straight
screwdriver, loosen a small red screw on top until it stops. Lift
or lower the wedge to the position desired and then tighten
the screw snugly (but do not over-tighten). Manually cycle the
wedge a couple of times after doing this to ensure that the
screw is snug, and the wedge moves correctly.
For the Surf Gate, there is a red hex bolt on the side of
the actuator. Opening this valve with a 3/8” wrench will allow
the Surf Gate to be moved into a closed position. Be sure
to retighten the bolt to prevent it from drifting open while
operating the boat.
