engine. The problem may be in the tower
shaft between the connector of the throttle
and the armature plate. The armature plate
may be "frozen", unable to move properly.
If the problem with shifting is at the
engine, the first place to check is the area
where the shift lever extends through the
exhaust housing. The bushing may be worn,
or corroded. If the bushing requires re-
placement, the engine powerhead must be
removed, see Chapter 3. Another cause of
hard shifting is water entering the lower
unit. In this case the lower unit must be
disassembled, see Chapter 8.
If hard shifting is still encountered at
the shift box when the controls are discon-
nected from the engine, the cables may be
corroded, and require replacment, or lack of
lubrication in the shift box has resulted in
excessive wear, or corrosion.
Unable to Obtain Full Shift
Movement or Full Throttle
Normally, this type of problem is the
result of improper shift box installation.
This area includes connection of the shift
and throttle cables in the shift box. If the
stainless steel inner wire was not heated and
the clamp did not hold the inner cable
(wire), the wire could slip inside the sleeve

and the cable would be shortened. There-
fore, if it is not possible to obtain full shift
or full throttle, the shift box must be re-
moved, opened, and checked for proper in-
stallation work. The inner wire could also
slip at the engine end of the control, but
problems at that end are very rare. Usually
if improper installation work has been done
at the engine end, the ability to shift at all
is lost, or the throttle cannot not be actuat-
ed.
