Sierra Tune Up Kit 18-5246, Replaces 898253T28, for Late Model V-6 4.3L Alpha/Bravo

The Sierra 18-5246 Tune Up Kit is a direct-fit ignition service kit designed for late model V-6, 4.3L Alpha/Bravo sterndrive engines. This kit brings together the ignition components needed to perform a complete tune-up in one package, restoring reliable spark and smooth engine performance without having to source individual parts separately. It is built to replace the OEM 898253T28 ignition kit, giving boat owners and marine technicians a straightforward, single-part-number solution for scheduled maintenance or ignition troubleshooting.

Keeping ignition components fresh is critical on marine engines, where exposure to moisture and vibration accelerates wear on distributor caps, rotors, and related ignition parts. Using a complete tune-up kit rather than mixing components from multiple sources helps ensure proper fit and consistent quality across all the included parts. The Sierra 18-5246 is intended specifically for late model V-6, 4.3L engines equipped with Alpha or Bravo sterndrives, so confirming this engine and drive combination before ordering is recommended.
