GENERAL
Maintenance to the transmission will normally consist of
the following items .
• Checking oil level or changing oil . Regular scheduled
oil changes are an important part of the transmission .
When properly adjusted detent ball must be seated
into shift handle holes .
• Checking pressure in each circuit (if a problem is
detected) .
LUBRICATION
Due to the various installation angles and oil cooler set-
ups, it may be necessary to adjust your oil level .
Check Oil Level
The transmission should be at operating temperature
(180° max .) to get an accurate oil level reading . Oil will
expand when it is heated . Oil will drain back from the
cooler . Expansion and drainback can significantly affect
oil level .
Warm Oil Level Check
When the transmission is at operating temperature,
place selector lever in neutral . Shut off engine . Carefully
remove transmission dipstick . Immediately insert clean
dipstick (Do not screw into housing to check level) and
read oil level .
NOTE: Oil level must be checked immediately after
engine shut-down to prevent an incorrect reading .
Oil drains back into transmission from the cooler and
cooler lines .
Add or remove oil if necessary . Repeat the above
checking procedure as required until oil is at the dip-
stick mark .
Cold Oil Level Check
For ease of checking the oil prior to engine start-up,
a cold oil level mark can be made . To find the cold oil
level mark, the oil level must first be set according to
the warm oil level checking procedure . Then, let the
boat sit overnight . Insert clean dipstick and read oil
level .
Put a mark on the dipstick at the cold oil level reading .
You can use the new mark the check the oil level when
cold . If oil level adjustment is needed, add oil to the
new mark .
