TRANSMISSIONS

OPERATING

TEMPERATURE

A

CAUTION:

If

the

transmission

fluid

temperature

is

too

high,

stop

the

engine

immediately

and

check

the

transmission

fluid.

Normal operating temperature of the

transmission

fluid

should be

in

the

range

of

122

0

F

(500

C)

to

212

0

F

(100

0

C).

A

maximum

temperature of

266

0

F

(130

0

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

Coolers

are

standard equipment

for

the

ZF

10

M,

12

M,

15

M,

15

MA,

15

MIv,

and

the

25

M

(no

cooler

is

necessary

for the ZF 5

M).

The cooler

is

a seperate part of the

transmission

which

pre-

vents

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, maintemance,

etc.

it might

only

last half

that

time.

INSPECT

FOR

LEAKAGE

AND

CORROSION

MAINTENANCE

Transmission maintenance

is

minimal.

Keep

the

exterior

housing

clean,

check

the

fluid

level

as

part of

your

regular

routine,

and

change

the

fluid

every

300

operating

hours.

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

strawbeny

cream).

Lay-up/Winlerize

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,

linkage,

and

attachments.

Look

for

corrosion of

the

end

fittings,

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 offwith

fluid

to

prevent internal

corrosion.

Reduce

the

fluid

level

before

putting

the

engine

back

into

service.
