Shimming (counter rotation model)
Shimming procedure
• Shim thickness is specified for the reverse gear shim (T1) and forward gear shims (T2).
• After selecting the pinion shims (T3), do not apply gear oil, grease, or sealant to the lower unit parts
to measure the backlash.
• When the backlash adjustment is completed for the reverse gear and forward gear, make sure to
select the propeller shaft shims (T4).
• When assembling the lower unit after shimming is completed, make sure to apply gear oil, grease,
and sealant to the specified areas.
