Measuring the forward and reverse
gear backlash
1. Remove the water pump assembly.
2. Set the gearshift to the neutral position.
3. Install the special service tool so that it
pushes against the propeller shaft.
NOTE:
Tighten the universal puller or center bolt
while turning the drive shaft until the drive
shaft can no longer be turned.
4. Install the backlash indicator onto the
drive shaft (22.4 mm [0.88 in] in diame-
ter), then the dial gauge onto the lower
unit.
5. Set the lower unit upside down.
NOTE:
Install the dial gauge so that the plunger
a
contacts the mark
b
on the backlash indica-
tor.
6. Slowly turn the drive shaft clockwise and
counterclockwise and measure the back-
lash when the drive shaft stops in each
direction.
7. Add or remove shim(s) if out of specifica-
tion.
