Description

Mercury Complete Gearcase 8M0172925 is a genuine Mercury OEM replacement lower unit for select 15 and 20 HP FourStroke outboards. This assembly is the Long (20-inch) configuration.

Compatible with select applications including:

Mercury 15 HP FourStroke
Mercury 20 HP FourStroke
Long-shaft applications where 8M0172925 is specified

This is the complete gearcase assembly, not the basic empty gearcase housing. Mercury parts breakdowns list the basic gearcase housing and internal components separately, while 8M0172925 is supplied as the complete Long gearcase.

This gearcase is identified as a 2.15:1 ratio Long configuration in Mercury OEM parts listings. Short and X-Long versions use different complete gearcase part numbers, so shaft-length configuration should be confirmed before ordering.

Supersedes/Replaces: 8M0134484, 8M0163177, 8M0163179

To Confirm Compatibility: Contact our team with your engine serial number at (727) 596-5929 before ordering.
