8. Move gear housing up toward driveshaft hous-
ing, while aligning shift shaft splines and water
tube with water tube guide (in water pump cover).
9. Place flat washers onto studs (located on either
side of driveshaft housing). Start a nut on these
studs and tighten finger-tight.
10. Start bolt at rear of gear housing inside trim tab
recess. DO NOT tighten bolt at this time.
11. Recheck shift shaft spline engagement and
correct if necessary.
IMPORTANT: Do not force gearcase up into place
with attaching nuts.
12. Evenly tighten 2 nuts which were started in Step
9. Torque to listing in “Torque Specifications,”
preceding.
13. After 2 nuts (located on either side of driveshaft
housing) are tightened, check shift operation as
follows:
a. Place guide block anchor pin into forward
gear position. Rotate flywheel clockwise
(viewed from top); propeller shaft should
rotate clockwise.
b. Place guide block anchor pin into neutral
position. Propeller shaft should rotate freely
clockwise/counterclockwise.
c. Place guide block anchor pin into reverse
gear position. Rotate flywheel clockwise
(viewed from top); propeller shaft should
rotate counterclockwise.
IMPORTANT: lf shifting operation is not as
described, preceding, the gear housing must be
removed and the cause corrected.
14. Install washers and nuts onto studs (located on
bottom center of anti-cavitation plate). Torque to
listing in “Torque Specifications,” preceding.
15. Install special flat washer and nut on stud at lead-
ing edge of driveshaft housing. Torque to listing
in “Torque Specifications,” preceding.
16. Torque bolt (started in Step 10) to listing in
“Torque Specifications,” preceding.
17. Install trim tab, adjust to position in which it had
previously been installed, and tighten securely.
18. Install plastic cap into trim tab bolt opening at rear
edge of driveshaft housing.
Propeller Installation
WARNING
When installing or removing propeller, because
of the engine’s ease in starting, be sure that the
remote control is in neutral position and that the
key switch is “OFF.” Place a block of wood
between the anti-cavitation plate and propeller to
prevent accidental starting and to protect hands
from propeller blades while removing or
installing nut.
1. To aid in future removal of the propeller, liberally
coat the propeller shaft splines with one of the
following Quicksilver products:
-- Anti-Corrosion Grease (92-78376A6)
-- Special Lubricant 101 (92-13872A1)
-- 2-4-C Marine Lubricant (92-90018A12)
-- Perfect Seal (92-34227--1)
2. Place forward thrust hub over propeller shaft with
shoulder side toward propeller.
3. Place propeller on propeller shaft and slide it up
against thrust hub.
