Outboard Rigging Guide - 2001
Cable Measuring
Use the following examples as a guide for mea-
surement. Obviously, different boats will require
different routing and therefore different lengths.
Control Box Adjustments
Proper control box adjustments are critical for
smooth and safe operation. Yamaha uses two
types of throttle control. Yamaha outboards 8,
F9.9, 25, & 30 pull the throttle cable to open.
Yamaha outboards T8, 9.9, 15, 40~C40 and larg-
er push the throttle cable to open. Shift cable con-
trol is the same for all outboards.
Yamaha 703/704/705 control boxes can be setup
as push or pull to open by changing one internal
component.
Rigging as efficiently as possible means setting
up the control box just once, without having to
open the box again to readjust the cable ends after
hookup to the motor. Refer to the following dia-
grams for proper cable end adjustments at the
control box. Using these settings at the control
box will insure the cable ends at the motor will
adjust properly.
ALL CABLES
Adjust the throttle friction so the handles do no
slip back while cruising.
NOTE: Twin engines using the 704 control box
must have the throttle cables synchronized. This
is to ensure the engines are running the same
RPM's with the throttle handles in line. This is
accomplished by adjusting the slack out of either
cable to give them the same throw. If cable slack
is adjusted and uneven RPM still remains, adjust
the pickup cams to help pickup some of the slack.
