Mercury Racing 500R 1.60:1 Counter-Rotation XXX-Long Complete Gearcase (White) 8M0224417

Mercury Racing Complete Gearcase 8M0224417 is a genuine Mercury OEM replacement gearcase assembly for select 500R 4.6L V8 Racing outboards. It is the counter-rotation, XXX-Long configuration finished in Cold Fusion White.

Compatible with select applications including:

• Mercury Racing 500R 4.6L V8
• Joystick Piloting applications
• R-Drive 1.60 gearcase systems
• Counter-rotation configurations
• XXX-Long shaft configurations

This gearcase uses a 1.60:1 ratio and a right-camber design. Mercury offers the 500R gearcase in multiple shaft lengths, rotations, and colors, so the exact configuration is important when selecting a replacement.

This is the complete gearcase assembly, not a basic empty housing. The related basic gearcase housings and internal components are serviced separately.

For comparison, 8M0224416 is the corresponding standard-rotation XXX-Long Cold Fusion White gearcase, while 8M0224417 is the counter-rotation version.
