3. Check that coupling centerlines align, by butting
propeller shaft coupler against transmission out-
put flange. Shoulder on propeller shaft coupler
should engage recess on transmission output
flange face with no resistance.
NOTE: Some propeller shaft couplers may not have
a shoulder on mating face. On these installations,
use a straight edge to check centerline alignment.

b. TO MOVE ENGINE TO THE LEFT OR
RIGHT: Loosen clamping screw and nut on all
four mount brackets; move engine to the left
or right as necessary to obtain proper align-
ment. On mounts which do have a slotted
hole, a small amount of adjustment can be
obtained with slot on front end of mounts.
Loosen lag screws (which fasten mounts to
engine bed) and move engine, as required.
Tighten lag screws securely.
c. After engine has been properly aligned:
Tighten engine mount nuts securely, and be
certain to bend one of the tabs on the tab
washer down onto flat of mount adjusting nut.
