Steering Eyes and Coupler Installation
1. Position engines so that they are facing straight
forward. (Distance between centers of threaded
pivot bolt holes in engine steering arms must be
equal to distance between propeller shaft
centers.)
2. Lubricate inside of rubber sleeves (Figure 9) and
slide on to coupler.
3. Slide rubber bushings (Figure 9) onto steering
eyes.
4. Thread steering eyes (Figures 9 and 10) into cou-
pler and adjust steering eyes so that distance be-
tween centers of pivot bolt holes in steering eyes
is the same distance as between centers of
threaded pivot holes in engine steering arms. Ex-
posed steering eye threads should be equal at
both ends of coupler and must not extend out of
coupler more than 2-3/4
″
(70mm).
WARNING
Both steering eyes must be threaded into cou-
pler 3/4
″
(19mm) minimum. Thread length of
steering eye is 3-1/2
″
(89mm), so exposed thread
must not extend out of coupler more than 2-3/4
″
.
Failure to adhere to this requirement could result
in steering system failure.
5. Lubricate steering eye threads, pivot bolts, and
ball joints with Quicksilver 2-4-C w/Teflon
(92-825407A12) before assembling.
6. Assemble steering eyes and coupler to top side,
front holes of steering arm with pivot bolts and
locknuts, as shown in Figures 7 and 10.
IMPORTANT: With steering eyes and coupler
installed and before tightening pivot bolts, check
engine alignment. Distance between pivot bolts
centers and distance between propeller shaft
centers must be equal for proper steering. If ad-
justment is necessary, remove pivot bolt from
one steering eye and turn eye in or out to correct
alignment. Both steering eyes MUST BE
threaded into coupler 3/4
″
(19mm) minimum.
7. Torque pivot bolts to 20 lbs. ft. (27.0 N m), then
thread self-locking nut (Figure 7) onto bolts and
torque nuts to 20 lbs. ft. (27.0 N
m).
WARNING
Both steering eyes MUST BE threaded into cou-
pler 3/4
″
(19mm) minimum, and jam nut (Figure 9)
must be secured against coupler to prevent cou-
pler from turning. Torque jam nut to 20 lbs. ft.
(27.0 N·m).
