Sierra 18-5269 Ignition Tune-Up Kit, Replaces GLM 71710, for Prestolite 8 Cylinder Distributors

The Sierra 18-5269 Ignition Tune-Up Kit is a complete breaker-point ignition service kit built for Prestolite 8 cylinder marine engine distributors. Rather than sourcing individual ignition wear parts separately, this kit bundles the four components most commonly replaced during a routine tune-up: a contact point set, a condenser, a rotor, and a distributor cap. Keeping these parts fresh helps maintain a strong, consistent spark, smoother idle, and reliable starting, since worn contact points and a failing condenser are among the most common causes of hard starting and misfires in point-type ignition systems.

Each part in the kit is manufactured to meet or exceed the specifications of the original equipment part it replaces, giving boat owners and marine technicians a straightforward, single-part-number way to stock a full tune-up service instead of tracking down four separate components. The kit is intended for engines using a Prestolite 8 cylinder distributor and is commonly stocked for scheduled maintenance, pre-season service, or as a repair kit when a boat is experiencing ignition-related running issues.
