EMP Outdrive Gasket Set, Replaces OMC 508105 - Part 27-00475

The EMP Outdrive Gasket Set, part number 27-00475, is a complete gasket and seal kit for outdrive service, engineered as a direct replacement for OMC part 508105. This kit gives boat owners and marine technicians everything needed to reseal the outdrive housing in a single package instead of sourcing each gasket or seal individually, helping prevent water intrusion and lubricant loss at the outdrive during reassembly.

The set includes an outdrive gasket (OEM 911836), an outdrive seal (OEM 911823), and an O-ring (OEM 911851), each matched to the original equipment part numbers so the replacement seals correctly against the mating surfaces on the first installation. Because every component in the kit is cross-referenced to its OEM number, installers can verify fit against the original hardware before starting the job.

At 0.037 pounds, this is a compact, lightweight kit intended for straightforward outdrive gasket replacement during routine maintenance or repair work. Ordering the full set as OMC 508105's direct replacement ensures the gasket, seal, and O-ring are replaced together, which is the recommended practice whenever an outdrive housing is opened.
