TRANSMISSIONS

INITIAL

OPERATION

All

HBW/ZF marine transmissions

are

test-run

on

a test

stand

with

the

engine

at

the

factory prior

to

delivery.

For

safety reasons

the

fluid

is

drained before shipment.

Fill the gearbox

with

Automatic Transmission Fluid

(DEXRON

II

or

DEXTRON III). The

fluid

level should

be

up

to

the

index mark

on

the

dipstick.

To

check

the

fluid

level,

just insert

the

dipstick,

do

not screw it

in.

Screw

the

dipstick

into

the

case after

the

fluid

level

is

checked and tighten.

Do

not

forg~t

the

sealing ring under

the

hexhead of the dipstick.

Check for leaks

and

change

the

fluid

after

the

first

25

hours,

also

make

a visual inspection of

the

coupling, oil cooler and

hoses,

and

shift cables.

Keep vent holes clear.

FLUID

CHANGE

Change

the

fluid

for

the

first

lime after about

25

hours

of

operation,

then

every

250

operating hours or

at

least once a

year

or

when

you

change engine oil.

Removing

the

fluid

Push a suction

pump

hose

down through

the

dipstick hole

to

the bottom of

the

housing

and

suck out

the

fluid.

(If space

allows,

use

the

transmission drain). Remove the drain plug

from

the

bottom of the transmission

and

allow

the

fluid

to

drain

into

a container,

then

reinstall

the

plug with its sealing

washer.

Wipe

down

the

transmission

and

properly dispose of

the

used

fluid.

After mnning the engine, shut down

and

recheck

the

fluid

level.

NOTE

: When changing the fluid, take care not

to

lose the

drain plug sealing washer. The drain plug will leak without

this sealing washer.

A

WARNING:

Never

pull

out

the

dipstick

while

the

engine

is

running.

Hot

fluid will

splash

from

the

dipstick

hole.

This

could

cause

severe

burns.

LOCKING

THE

PROPELLER

Locking of the propeller shaft by

an

additional brake

is

not

required: use

the

gear shift lever position opposite your

direction of travel for

this

purpose. Never put

the

gear shift

in

the

position corresponding

to

the

direction of travel of

the

boat.

WHEN

UNDER

SAIL

OR

BEING

TOWED

Rotation of

the

propeller without load

(in

neutral),

such

as

when

the boat

is

being sailed,

being

towed,

or

anchored

in

a

river,

as

well

as

operation of

the

engine

with

the

propeller

stopped (for charging

the

battery),

will

have

no

·

detrimental effects on

the

transmission

DAILY

OPERATION

0 Check the transmission

fluid.

D Visually check the gear shift linkage

and

transmission.

d Start

the

engine

in

neutral, allowing a

few

minutes

at

idle

to

warm

the

fluid.

0 Shift into

gear.

NOTE

:

Too

low an idle speed will produce a chattering noise

from the transmission gear and damper plate.

In

such cases

the idle speed should be increased
