Sierra 18-5002 Ignition Tune Up Kit, Replaces OMC 172523, for Evinrude Outboards

The Sierra 18-5002 Tune Up Kit is a complete ignition service kit for Evinrude outboard engines, built to restore reliable spark and smooth running to an aging or worn ignition system. Sierra engineers this kit to meet or exceed the performance of the original equipment parts it replaces, and Sierra supplies OEM engine manufacturers and boat builders with quality parts every day, so the components in this kit are made to the same standard as what left the factory.

Inside the kit you get a contact set (2 included) and a condenser (2 included), the two wear items that cause hard starting, misfires, and rough idle as a points-type ignition ages. Replacing both together during a tune-up is the standard practice, since a worn condenser will quickly burn out a fresh contact set if left in place. The kit carries a machined exterior finish for a precise fit against the factory ignition components it is designed to service.

This kit is designed to replace OMC part number 172523 and is intended for Evinrude outboard engines that use this ignition service kit. Sierra backs the 18-5002 with its standard quality warranty.
