FITTING ON THE TOP OF THE CASE
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 (1" with sealing washer)
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 running the engine,
shut down and re-check the fluid level.

INITIAL OPERATION
Remove the dipstick and fill the gear box with automatic
transmission fluid (ATF) Dexron III. Fill the transmission
with the recommended capacity of fluid.
Model PRM80-l.O U.S. pints (0.6L)
Model PRM 120-1.4 U.S. pints (0.8L)
NOTE :
Always clean the area around the dipstick plug
before filling with fluid. Replace the dipstick by screwing it
down.
Run the engine to warm up the fluid and after shutting down
the engine, re-check the fluid level.
CHANGING THE TRANSMISSION FLUID
Change the fluid for the first time after about 25 hours of
operation, then every 250 operating hours or at least once
a year or when you change engine oil. Check for leaks and
make a visual inspection of the shift cables and shaft
coupling.

GEAR SHIFTING
The engine must be at idle. Pause in neutral before
selecting ahead or astern. Transmission models PRM 80 and
120 are ideal for single lever engine controls, controlling
both the throttle and the gear shift at one time.
A
WARNING:
When shifting gears, bring the engine
throttle to idle and pause in neutral before shifting
ahead or astern.
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, 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
