Be sure that the threaded rods are bottomed out
in the rod ends before tightening the jam nuts
against the rod ends.
The
two threaded rods must be threaded into
the center tube far enough
so that the threads
can be seen through the
two inspection holes at
either end of the center tube. This determines
the maximum extension possible. The minimum
centerline distance is 470 mm (18.5 in). Do not
tighten the jam nut.
error adjustments June have to be made in order to
maximize the performance of the dual engines.

Turning the center tube in one direction will
create “toe-in,’’ while turning the center tube in
the opposite direction will create a “toe-out’’
attitude for the
two engines. An 11/16 inch flat
has been provided at the center of the center
tube to facilitate turning the tube.
Always tighten the jam nut against the center
tube before doing any performance evaluations.
LNOTlCE I
Extending the bar, so you cannot see the
threads through the inspection holes, can make
the tie bar weak. A weak
tie bar can flex and
adversely effect steering.
Do not exceed the
maximum allowable extension of
749 mm
(29.5 in).
Grease and place the bushing inserts through
the rod eyes. Mount the bar with the bushing
heads under the steering plates.
The bar can
be mounted on top
of the steering plates in
some applications.
Place a flat washer over the 3/8 inch hex head
bolt and insert the bolt through the bushing in
the rod end from the underside. Thread this bolt
into the forward hole on the steering plate found
on the front of the engine.
Thread the self-locking nut onto the bolt portion
that protrudes above the steering plate and
tighten securely.
ADJUSTMENT
Different hull configurations June require slightly
different set-up and adjustments. Some trial and
I NOTICE I
Leaving the jam nuts loose can cause the rod
ends
to misalign. Misaligned rod ends can
adversely effect steering. After making
adjustments, always tighten all jam
nuts
securely before operating the boat.
There are three jam nuts on the bar. Two of
these are tightened down against the tie rod
ends and the third jam nut is tightened against
the center tube. There is no jam nut against the
other end of the center tube because this allows
for either engine to be tilted independently.
I NOTICE I
If the engines are not allowed to tilt
independently of each other, the steering plates
and related steering components June become
bent when the engines are tilted.
Motors with toe-out (viewed from the stern) will
ensure better boat stability. It is best if the exhaust
wakes of
two motors join 9-12 meters (30-40 ft)
astern.
