.INITIAL OPERATION
Before starting the engine, remove;: the dipstick and fill the
transmission with au1<>matic transmission fluid (ATE)
Dextron 11 or Dextran Ill. Fill to the mark on the dipstick.
Do not overfill. .
.Run the engine to warm up the fluid and after shutting down
.the engine, re-check the fluid level.

Model PRM 12Q-l.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 .
CHECKING THE FLUID LEVEL
Thread
the dipstick fully into the case, then I!nscrew it and
observe the fluid level.
CHANGING THE. TRANSMISSION FLUID
Change the f1l!id for the first time at'ter about 25 hours of
operation, then every 250 operatiog hours or at least once a
year or when you change engine fluid. Check for leaks and
malee a visual inspection of the shift' cables and shaft
coupling. 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). Relilove
. 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 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 (lut the dipstick while the
inglne is running. Hot fluid will splash from the
dipstick hole. This t;(luld cause severe burns.
DAILY OPERATION
o
Check the transmission fluid.
o
VISually check the gear shift linkage and transmission.
o
Start the engine in neutral, allowing a few minutes at
idle to wann the fluid.
o .
Shift into gear.
NOTE: Too Iowan idle speed will produce a chattering noise
from the transmission gear and damper plate. In such cases
the idle speed should be increased. .
GEAR SHIFtiNG
The engine must be at Idle. PaUse in neutral
befo~e
seleetiog ahead or astern, Transmission models PRM 80 and
120 are ideal for single lever controls, controlling both the
throttle and the gear shift at one time.
A
WARNING:
When shifting gears, bring the engine
thr(lttle
t(l
idle and pause in neutral before shifting
ahead (lr 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 a load, such as when lhe
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), willhave no detrimental effects
on the transmission.
