5.
Calculate the pinion shim thickness (T3)
as shown in the examples below.
NOTE:
“P” is the deviation of the lower case dimen-
sion from standard. The “P” mark
a
is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the “P”
mark is unreadable, assume that “P” is zero
and check the backlash when the unit is
assembled.
Example:
If “M3” is 50.75 mm and “M4” is 30.52 mm
and “P” is (–5), then
T3 = 82.00 + (–5)/100 – 50.75 – 30.52 mm
= 82.00 – 0.05 – 50.75 – 30.52 mm
= 0.68 mm
6.
Select the pinion shim(s) (T3) as follows.
Example:
If “T3” is 0.68 mm, then the pinion shim is
0.65 mm.
If “T3” is 0.70 mm, then the pinion shim is
0.68 mm.

Measuring the forward and reverse
gear backlash
1.
Remove the water pump assembly.
2.
Set the gear shift to the neutral position
at the lower unit.
3.
Install the special service tools so that it
pushes against the propeller shaft.
NOTE:
Tighten the center bolt while turning the drive
shaft until the drive shaft can no longer be
turned.
Calculation formula:
Pinion shim thickness (T3) =
82.00 + P/100 – M3 – M4
