7. OPERATION OF STANDARD REVERSING
GEAR
Several types of reversing gears are
used on UNIVERSAL engines. The
operation, however, is the same in
all cases. See Paragraph 6, Sec-
tion IV, for detailed operation.
a. Moving the lever to the forward
position (toward engine) places the
transmission in forward drive.
b. Moving the lever to the stern
position (away from the engine)
places the transmission in reverse
drive.
c. Moving the lever to the center
position puts the transmission in
neutral and no power is delivered
to the propeller shaft.
8. OPERATION OF HYDRAULIC REVERSING
GEARS
a. The hydraulic reversing gear is
basically a hydraulically operated
multiple disc clutch in comb.ination
with a hydraulically operated
planetary reversing gear train. The
-)6-
gear positions are stamped on the
top cover. See Paragraph 6, Section
IV for detailed operation.
(1) Moving the lever, on the top
cover, to the "F" position places
the transmission in forward drive.
(2) Moving the lever to the "R"
position places the transmission
in reverse drive.
() Moving the lever to the center,
or "N" position places the trans-
mission in neutral.
b. The design of the reversing gear
is such that the operation of both
the forward and reverse drives is
almost instantaneous with the move-
ment
of the shifting control lever.
This condition exists even at low
speeds. For this reason it is not
necessary to race the engine to ob-
tain good shifting characteristics.
In fact, it is advisable to shift
at low speeds, below 1400 RPM, and
preferably in the 800 to 1000 RPM
range. Shifting at conservative
engine speeds will avoid damage to
the boat, engine reversing gear,
