Follow the procedure below to adjust forward gear /
pinion gear.
Prior to adjustment
1) Install standard pinion gear back-up shim thickness
according to ± design specification mark on the gear.
2) Correctly assemble driveshaft bearing housing,
driveshaft, forward gear, pinion gear and related
components. Refer to “Lower Unit Assembly” (Page
3A-16).
Do not install reverse gear at this time.

2) To check driveshaft thrust play, push the forward
gear inward and hold it in this position. Slowly push
the driveshaft downward completely, then slowly pull
the driveshaft up and read the maximum thrust play.
Driveshaft thrust play
0.4 – 0.6 mm (0.016 – 0.023 in.)
• If thrust play is larger than specified, the forward
gear back-up shim thickness must be increased.
• If thrust play is smaller than specified, the forward
