Mercury Marine Retainer/Seal Kit | Boat Supply Store
This Mercury Marine Retainer/Seal Kit addresses critical seal integrity within sterndrive and outboard engine lower units. Properly functioning seals prevent water ingress and lubricant washout, maintaining essential lubrication for gears and bearings operating at high rotational speeds up to 4000 RPM. A failing seal can lead to catastrophic internal component damage, especially in saltwater environments common along the Texas coast.
