Wear safety glasses to avoid personal injury, and set compressed air pressure to less than 25 psi (172 kPa).

IMPORTANT: Clean and inspect all parts during disassembly. Replace any damaged parts, seals, O-rings, and gaskets.

Before disassembling the gearcase, examine the following:
• Gearcase Housing — Check for visible damage to skeg, strut, anti-ventilation plate, bullet, and mating surface. Check seal areas for visible signs of lubricant leakage.
• Propeller Shaft — Check for bent or damaged shaft. Check for twisted splines and damaged
threads.
• Shift Rod — Check for bent, or binding rod.
• Hydrostatic Seal Grooves — Must be in good condition to help prevent propeller ventilation.

1. Hydrostatic seal grooves 007665

• Gearcase Anodes — If anodes have eroded to two-thirds their original size, they must be
replaced.

• Drive Shaft — Check splines for visible damage, twisting and wear. Severe spline wear indicates the exhaust housing or gearcase has been distorted, possibly by impact damage.

Remove the propeller and mounting hardware Drain and inspect oil as described in Gearcase Lubricant on p. 73. Remove gearcase. Refer to GEARCASE REMOVAL AND INSTALLATION on p. 280.
