Mercury Complete Gearcase 8M0235793 is a genuine Mercury OEM replacement lower unit for select 5.7L V10 outboards. This assembly is the XXL, silver SeaPro configuration and is used with Mercury's 6.44-inch gearcase platform.

Compatible with select applications including:

• Mercury 350 HP 5.7L V10 Verado
• Mercury 350 HP 5.7L V10 SeaPro
• Mercury 400 HP 5.7L V10 Verado
• XXL configurations where 8M0235793 is specified

This is the complete gearcase assembly, not the basic gearcase housing. The corresponding basic SP gearcase housing is serviced separately as 8M0228005, along with the internal gears, shafts, bearings, seals, and other lower-unit components.

Mercury offers this V10 gearcase family in Long, XL, XXL, and XXXL configurations, along with separate counter-rotation versions. Shaft length and exact gearcase configuration should be verified before ordering.
