Mercury Marine Engine Drive Plate Assembly 350, 454, 7.4L & 8.2L

The Mercury Marine 862975A1 Engine Drive Plate Assembly is a genuine factory OEM component engineered to deliver reliable performance in MIE inboard marine applications. Designed as a direct-fit replacement, this driveplate assembly connects the engine to the drivetrain with precision tolerances that meet or exceed original factory specifications.

This part supersedes several earlier Mercury Marine part numbers — 808028, 808028F1, 808028A1, and 862047A1 — making it the current-production replacement for a wide range of inboard engine builds.
