Sierra Condenser 18-5345 for GM 4/6/8 Cyl & Ford 302 Marine Distributors (Replaces Mercury Marine 33662)

The Sierra 18-5345 is a marine ignition condenser designed for Prestolite conventional ignition distributor systems used on a wide range of gas inboard and sterndrive engines. The condenser is a core tune-up component that works alongside the contact set (points), distributor cap, and rotor to suppress arcing at the breaker points and keep the ignition system firing reliably. It is built with a machined exterior for a precise fit inside the distributor housing.

This condenser is used across multiple engine families with Prestolite-style distributors, including 4-cylinder engines fitted with the 1C IGW-4118A and 1C IGW-4301 distributors, 6-cylinder 3.8L engines using the IBM-7014A distributor, GM 305/350/454 cid V8 engines using the IBM-7011 and IBM-7013 distributors, and Ford 302 V8 engines using the IBM-7007 and IBM-7007A distributors. Because it is compatible across so many Prestolite conventional ignition setups, it also cross-references to condensers used by Chris-Craft, Chrysler Inboard, Crusader, Mercury Marine, OMC, PleasureCraft, and Volvo marine engines.

As a wear item, the condenser should be replaced any time the contact set is replaced during a tune-up, since a weak or failing condenser causes premature point burning, hard starting, and rough idle. The 18-5345 is sold individually and is sized to fit directly in place of the original equipment condenser on these distributor applications.
