ZF MARINE TRANSMISSIONS
OPERATING TEMPERATURE
A CAUTION: If the transmission "uid temperature is
too high, stop the engine immediately and check the
transmission "uid.
Nonnal operating temperature of the transmission fluid
should be in the range of 122' F (50' C) to 212' F (100' C).
A maximum temperature of 266' F (130' C) may be only
reached for a short time.
Make certaIn there is enough space around the transmission
to provide good ventilation and cooling.
TRANSMISSION COOLER
Transmission coolers are standard on ZFIOM(HBWIOO),
ZFI2M(HBWI24), ZFI5M(HBWI50),
ZFI5MA(HBWI50A),
ZFI5MIV(HBWI50V) and the
ZF25M(HBW250). No cooler is needed for the ZF35 or the
ZF50.
The cooler is a separate part of the transmission which
prevents any possibilities of coolant diluting the transmission
fluid. However, the continued flow of coolant thru the cooler
will, in time, erode the inside of the cooler causing external
leaks.
A transmission cooler may last ten years or more but, in
some circumstances, depending on operating hours, tropical
waters, maintenance, etc. it might only last half that time.
WESTERBEKE recommends having a spare cooler aboard.

MAINTENANCE
Transmission maintenance is minimal. Keep the exterior
housing clean, check the fluid level as part of your regular
routine per operational checks. Change the fluid after initial
25 hour break-in and then at 300 hours of operation or at
least once a seaSOD.
Periodically inspect the transmission and the cooler for leaks
and corrosion. Make certain the air vent is clear and when
checking the fluid level look for signs of water contamination
(fluid will appear as strawberry cream).
Lay-up/Winterize
Storage requires special care. Follow these procedures:
o Drain water from the transmission oil cooler and replace
with a proper mixture of antifreeze coolant.
NOTE: This operation will normally occur when the
engine raw water cooling system is properly winterized.
o Clean up the transmission and touch up unpainted areas
(use heat resistant paint).
o Fill the transmission with Dextron III ATF fluid to
prevent internal corrosion (extended storage only, twelve
months or more).
o Loosen attaching hardware from the transmission output
flange and propeller shaft coupling flange before
removing
the boat from the water. Separate the flanges
and spray with lubricant.
o Inspect the gear shift cable, liokage, and attachments.
Look for
corrosion of the end fitrings, cracks or cuts in
the. conduit, and bending of the actuator rods. Lubricate
all moving parts.
NOTE: If the transmission is to be stored for a long time
(twelve months or more), it should be topped off with
fluid to prevent internal corrosion. Reduce the fluid level
before putting the engine back into service.
