Mercury 250-300 HP L6 Verado 1.85:1 XL Complete Gearcase 8M0117260

Mercury Complete Gearcase 8M0117260 is a genuine Mercury OEM replacement lower unit for select 250 and 300 HP L6 Verado outboards. This assembly is the cambered, standard-rotation, X-Long configuration with a 1.85:1 gear ratio.

Compatible with select applications including:

• Mercury 250 HP L6 Verado
• Mercury 300 HP L6 Verado
• 250/300 HP JPO applications
• X-Long configurations where 8M0117260 is specified

The 8M0117260 gearcase uses Mercury's 5.44-inch torpedo platform and is specifically identified for 250/300 HP JPO applications. It should be distinguished from the standard non-cambered 1.85:1 gearcases used across the broader 200-300 HP L6 Verado family.

This is the complete gearcase assembly, not a basic empty gearcase housing. Mercury offers separate Long, X-Long, XX-Long, standard-rotation, and counter-rotation gearcases within this family, so the exact engine and gearcase configuration should be confirmed before ordering.
