NOTE:
When installing the gearbox, make cenain that shifting

not impeded by restricted movability
of
the Bowden cable

rod linkage,
by

A shift cable attachment is pro-

MAINTENANCE
Transmission
Fluid
To ensure trouble-free operation
of
the gearbox, only use
Automatic Transmission Fluid (ATF). (Dexron
II
or
III).
Capacity
Add the fluid quantity for the proper model transmission to
the gearbox. After filling, check the fluid level with the dip-
stick. Adjust level as needed. Install the dipstick with the
sealing washer. operate unit, check fluid, check for leaks.

Fluid
Change
Change the fluid for the first time after about
50
hours
of
operation, then every
250
operating hours or at least once a
year or when you
change

oiL
When changing the
fluid, also check the gearbox cooling device and clean or
replace
it
as necessary.
NOTE:
When changing the fluid. take care
flot
to lose the
drain plug sealing

The drain plug will leak without

Checking
the
Bowden
Cable
or
Rod
Linkage
The Bowden cable or rod linkage should be checked at regu-
lar intervals. Check the neutral position
of
the operating lever
(on the control console) and the actuating lever (on the gear-
box). The minimum lever travel from the neutral position
to
the operating positions (0 - A = 0 - B) should be 35mm for
the outer and 30mm for the inner pivot point. Make certain
that
these minimum values arc safely reached. Check
the
cable or rod linkage for easy movahility and proper attach-
ment.
Propeller
Shaft
Alignment
The engine's transmission must be exactly aligned with the
propeller shaft. Misalignment will create excessive shaft and
bearing
wear
and can cause the transmission'5 rear seal
to
leak fluid.
The shaft/transmission coupling alignment should be checked
periodically and always when the boat
is
being recommis-
sioned after winter storage.
Lay-up/Winterize
If
the transmission
is
not used for periods
of
more than one
year,
it
should he completely filled with transmission fluid to
prevent corrosion.
Protect the input shaft and the output
flange
by
means
of
an
anticorrosive coating,
as
required.
