NOTE: If, while performing Step 11, the drive shaft
splines will not align with the crankshaft splines, place
a propeller onto propeller shaft and turn it counter-
clockwise as the gear housing is being pushed to-
ward drive shaft housing.
NOTE: During installation of gear housing, it may be
necessary to move the shift block (located under
cowl) slightly to align upper shift shaft splines with
shift shaft coupler splines.
11. Position gear housing so that the driveshaft is pro-
truding into drive shaft housing.
12. Move gear housing up toward drive shaft housing,
while aligning upper shift shaft splines with shift
shaft coupler splines, water tube with water tube
seal, and crank shaft splines with drive shaft
splines.
13. Install 4 bolts and washers (two each side).
14. Install locknut and washer.
15. Torque bolts and locknut (or nuts only if applica-
ble) to 40 lbs. ft. (54 N·m).

16. Check shift operation as follows:
a. Place shift lever in forward gear. Gear housing
should ratchet when propeller shaft is turned
clockwise and resistance should be felt when
propeller shaft is turned counterclockwise.
b. Place shift lever in neutral. Propeller shaft
should rotate freely in either direction.
c. While rotating propeller shaft, place shift lever
in reverse gear. Resistance should be felt when
propeller shaft is rotated in either direction.
IMPORTANT: If shift operation is not as described,
preceding, the gear housing must be removed
and the cause corrected.
