ACCESSORIES
7-1 INTRODUCTION
Boat accessories are seldom obtained
from the original equipment manufacturer,
except in the case of the electric shift unit.
The electric shift box is considered a part of
the new engine. Therefore, unless an owner
made a change, the electric shift unit with
the engine is probably original engine manu-
facturer equipment. Mechanical shift units
are sold and installed separately.
Shift boxes, steering, bilge pumps, blow-
ers, and other similar equipment may be
added after the boat leaves the plant. Be-
cause of the wide assortment, styles, and
price ranges of such accessories, the distrib-
utor, dealer, or customer has a wide selec-
tion from which to draw, when outfitting
the boat.
Therefore, the procedures and sugges-
tions in this chapter are general in nature in
order to cover as many units as possible, but
still specific and in enough detail to allow
troubleshooting, repair, and adjustment for
each of these accessories. Proper operation
will do much for maximum comfort, perfor-
mance, and enjoyment.
Complete procedures for removal, in-
stallation, and adjustment of four shift ar-
rangements are covered in this Chapter:
The old-style manual shift; new updated
manual shift; electr ic shift; and the push-
button shift mechanism. These shift boxes
are all considered original Johnson/Evinrude
equipment.
7-2 SHIFT BOXES
DESCRIPTION
Undoubtedly, the most used accessory on
any boat is the the shift control box. This
unit is a remote-control device for shifting
the outboard and at the same time con-
trolling the throttle. The shift box on OMC
equipped boats is considered an accessory,
except in the case of the electric shift.
Therefore, many installations may have oth-
er than a factory installed unit. OMC
equipped boats may be equipped with one of
four
different type shift boxes: The old-
sty le manual shift; new updated manual
shift; electric shift; and the pushbutton shift

The mechanical shift box units have two
levers, a long lever handle and a short lever
handle. The long handle controls the throt-
tle and the short one the shift mechanism.
The electric shift units, including the push-
button models, have only one lever handle
for control of the shift and throttle. The
shift box installed with Johnson engines has
one handle for shifting, and another at the
