Sierra Tune-Up Kit 18-5247, Replaces 898253T28, for Late Model V-6 4.3L Alpha/Bravo Engines

The Sierra 18-5247 Tune-Up Kit is an engine ignition tune-up kit built for late model V-6, 4.3L engines equipped with Alpha or Bravo sterndrives. It is designed as a direct replacement for OEM part 898253T28, giving boat owners and marine technicians a straightforward way to restore ignition system performance during a scheduled tune-up or when addressing a rough-running or misfiring engine.

Sierra manufactures this kit to meet or exceed the specifications of the original equipment part it replaces, and the components are engineered to hold up to the demands of continuous marine operation, including exposure to moisture, vibration, and temperature swings that are harsher than typical automotive conditions. Because Sierra supplies parts to OEM engine manufacturers and boat builders, this kit is built to the same fit and function standards as the factory original.

Part number 18-5247 is intended specifically for late model V-6, 4.3L Alpha/Bravo applications. Sierra also offers a separate tune-up kit, 18-5291, for late model V-8 (Alpha/Bravo 350 Mag, 5.0L, and MX 6.2L) engines, so it is important to confirm engine size and drive type before ordering to make sure you get the correct kit for your application.
