Mercury 40-60 HP Command Thrust X-Long Complete Gearcase 8M0118592

Mercury Complete Gearcase 8M0118592 is a genuine Mercury OEM replacement gearcase for select 40-60 HP Command Thrust outboards. This is the Generation 5 X-Long configuration designed for compatible Command Thrust applications.

Compatible with select applications including:

• Mercury 40 HP FourStroke Command Thrust
• Mercury 50 HP FourStroke Command Thrust
• Mercury 60 HP FourStroke Command Thrust
• X-Long shaft configurations where 8M0118592 is specified

Mercury identifies 8M0118592 as GEARCASE ASSY - XLONG CT GEN.5, while the corresponding Long configuration is part number 8M0118591.

This is the complete gearcase assembly, not an empty gearcase housing. The related basic, non-completed gearcase assembly is sold separately under part number 8M0118594.

Command Thrust gearcases use a larger gearcase and propeller platform than the standard gearcase offered on compatible horsepower models. Because Mercury offers different gearcase configurations within the 40-60 HP family, confirm the engine serial number and shaft configuration before ordering.
