Example:
If “M” is 24.00 mm and “F” is (+5), then
T1 = 24.50 + (+5)/100 – 24.00 mm
= 0.50 + 0.05 mm = 0.55 mm
If “M” is 24.00 mm and “F” is (–5), then
T1 = 24.50 + (–5)/100 – 24.00 mm
= 0.50 – 0.05 mm = 0.45 mm
3. Select the forward gear shim(s) (T1) as
follows.
Example:
If “T1” is 0.55 mm, then the forward gear
shim is 0.52 mm.
If “T1” is 0.45 mm, then the forward gear
shim is 0.42 mm.
Selecting the reverse gear shims
NOTE:
The F100C does not contain reverse gear
shims, therefore shimming is not necessary.

Measuring the forward 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.
Calculation formula:
Forward gear shim thickness (T1) =
24.50 + F/100 – M
