Mercury Marine 3.0L 150hp EFI FourStroke Outboards 300 Hour Maintenance Kit
The Mercury Marine part number 8M0163132 300 Hour Maintenance Kit is designed to make routine maintenance straightforward and reliable for owners of Mercury 3.0L 150hp EFI FourStroke outboards. Engineered for engines with serial number 1B905505 and above, this genuine OEM kit delivers everything needed for a comprehensive 300-hour service interval in a single convenient package.
Each component in this kit is manufactured to Mercury's exact tolerances, ensuring proper fitment and consistent performance. By using OEM parts rather than aftermarket alternatives, owners can be confident that their engines receive the same quality components used in the original build. This level of precision reduces the risk of premature component failure and helps maintain the engine's long-term reliability, whether operating in freshwater or saltwater environments. Anodes must be purchased separately based on your specific application and water type.
This kit is well suited to center consoles, bay boats, pontoons, fishing boats, offshore skiffs, and family runabouts—any platform powered by the Mercury 150 EFI FourStroke 3.0L outboard. It is particularly valuable for boaters who push their engines through demanding conditions and accumulate high hours during the season.
