Indmar Marine Engines

A separate owner’s manual
covering basic maintenance
is provided with each trans-
mission. The transmission
fluid must be changed and
the filter cleaned after the
first 10-20 hours of opera-
tion and once each year
thereafter. Refer to the
transmission owner’s
manual for information.
The transmission is water
cooled by a heat exchanger
connected to the engine
cooling system. The trans-
mission fluid level should be
checked daily. Fluid level is
to be maintained at a level
between the “Full” and
“Add” marks on the
transmission dipstick.
Overfilling the transmission with fluid will cause the seals
to leak, and eventually lead to overheating. When there
is too little fluid, over-heating will result.
If the engine uses the Walters V-Drive, it is equipped with
a ZF Hurth in-line transmission for shifting. Be aware that
the Walters V-Drive uses motor oil for lubrication, while
the ZF Hurth transmission uses Automatic Transmission
Fluid. The Walters V-Drive also has a low oil pressure
sensor and a dashboard mounted light. If low oil
pressure is sensed, this lamp will light indicating the
problem. Shut down the engine and check the transmis-
sion fluid level. Refer to Section 4, Check Transmission
Light for more information.
If transmission service is required, note the Serial
Number of the transmission stamped onto the ID plate
on the top of the transmission housing. It is good
practice to note the serial number and keep it with other
owner related information.
Checking/Adding Transmission Fluid
Transmission fluid may be hot.
NOTE: Refer to page 6-18 for correct transmission and
fluid capacities for your model of transmission.
