MerCruiser Bravo One Sterndrive 100 Hour Maintenance Kit

Mercury Marine MerCruiser Bravo One Sterndrive 100 Hour Maintenance Kit

The Mercury Precision Parts 100 Hour Maintenance Kit (part number 8M0147056) bundles all the components required for a complete 100-hour sterndrive service into a single, convenient package. Designed specifically for MerCruiser Bravo One sterndrives manufactured in 1988 and newer, this genuine OEM kit eliminates the need to source individual parts and ensures every component meets Mercury Marine's exact engineering standards for fit, function, and durability.

The O-ring kit provides tight, reliable sealing at critical junctions, preventing seepage and giving you confidence that the drive is properly secured after installation. The aluminum anode kit works continuously to protect the sterndrive from galvanic corrosion in both saltwater and freshwater environments, preserving performance and longevity between service intervals. The gearcase drain seals ensure clean, leak-free gear lube changes that support crisp, smooth gear engagement and protect the lower unit over the long term.

Choosing genuine Mercury OEM parts means each component is engineered and tested specifically for the Bravo One system. Mercury's decades of manufacturing experience are reflected in the precision fitment and corrosion resistance these parts deliver — attributes that aftermarket alternatives often cannot consistently match in demanding marine environments.

To complete the 100-hour service, pair this kit with genuine Mercury 4-Stroke Marine Engine Oil and Mercury Premium Gear Lube (858058K01), both sold separately. Mercury parts and accessories are backed by decades of experience in engineering, testing, and manufacturing to provide the best fit, function, and performance.
