b. Models with V-Drive Transmission: Lift en-
gine into boat and position on engine bed so
that enough propeller shaft protrudes
through transmission and output flange for
propeller shaft coupler to be attached. Then,
install coupler and position engine so no gap
can be seen between coupling faces when
butted together. Adjust engine bed height,
if necessary, to obtain proper alignment. DO
NOT use mount adjustments to adjust engine
position at this time.
!
CAUTION
Center lifting eye (located on top of thermostat
housing) is used for engine alignment only. DO
NOT use to lift entire engine.
!
CAUTION
DO NOT allow lifting sling to hook or compress
engine components or damage to them will
occur.
2.
Attach a suitable sling to lifting eyes on engine.
(Refer to “Removal” section for location of
lifting eyes.)
IMPORTANT: Engine bed must position engine
so that a minimum of 1/4 in. (6 mm) up-and-down
adjustment still exists on all four mounts after
performing final alignment. This is necessary to
allow for final engine alignment.
c
a. Models with Down Angle Transmission:
Lift engine into boat and position on engine
bed so that transmission output flange and
propeller shaft coupler are visibly aligned so
no gap can be seen between coupling faces
when butted together. Adjust engine bed
height, if necessary, to obtain proper align-
ment. DO NOT use mount adjustments to ad-
just engine position at this time.
