The condenser is a core electrical component of a points-type ignition distributor, working alongside the contact set to suppress arcing at the breaker points and help maintain a clean, consistent spark as the engine runs. A rectangular, flange-mount design allows it to install directly onto the distributor housing in the factory location, making it a straightforward replacement during a tune-up or when restoring reliable ignition performance on an aging conventional-ignition setup.\u003c\/p\u003e\u003cp\u003eLike other Sierra electrical parts, the 18-5338 is built to meet or exceed the performance of the original equipment part it replaces, and Sierra manufactures it to marine-duty standards suited to the humidity, vibration, and corrosion exposure of an engine compartment. It ships as a single condenser unit, ready to swap in place of a worn or failing original condenser without modification.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-5338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Condenser\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Rectangular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Flange Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999236623\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser V-8 engines with Mallory conventional ignition\u003c\/li\u003e\n\u003cli\u003eAll Mallory distributor applications, 1998 and earlier\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5338 condenser fit?\u003c\/strong\u003e The Sierra 18-5338 condenser fits Mercruiser V-8 engines equipped with Mallory conventional ignition, covering all Mallory distributor applications from 1998 and earlier.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5338 a genuine Sierra part or aftermarket?\u003c\/strong\u003e 18-5338 is Sierra's own manufacturer part number, not a third-party aftermarket clone, and Sierra states its electrical parts meet or exceed the original equipment component they replace.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape and mounting style is this condenser?\u003c\/strong\u003e This condenser has a rectangular body and a flange mount design, allowing it to bolt directly to the distributor housing in the original factory position.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5338 condenser weigh?\u003c\/strong\u003e The Sierra 18-5338 condenser weighs 0.06 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this part?\u003c\/strong\u003e Ordering the Sierra 18-5338 gets you one condenser unit, sold individually rather than as part of a kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this condenser work with a Mercruiser V-8 that has electronic ignition instead of points?\u003c\/strong\u003e No, the 18-5338 condenser is built specifically for Mallory conventional (points-type) ignition on Mercruiser V-8 engines, not electronic ignition systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5338 replace the original condenser on a 1998 or older Mallory distributor?\u003c\/strong\u003e Yes, the 18-5338 is intended as a direct replacement condenser for Mallory distributor applications dated 1998 and earlier.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a condenser used for in a marine ignition distributor?\u003c\/strong\u003e In a points-type distributor like those using Mallory conventional ignition, the condenser (the 18-5338 in this case) suppresses arcing across the breaker points so the ignition system produces a cleaner, more consistent spark.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5338 condenser sold with related tune-up parts like the contact set, rotor, or cap?\u003c\/strong\u003e No, the 18-5338 is the condenser only; the contact set, rotor, and cap for the same distributor line are separate Sierra part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-5338 condenser?\u003c\/strong\u003e The UPC for the Sierra 18-5338 condenser is 030999236623.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988209053915,"sku":"SIE-18-5338","price":8.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5338_lg__28010.1558128815.500.750.jpg?v=1785188526","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-ignition-condenser-for-mercruiser-v-8-with-mallory-conventional-ignition-replaces-oe-16-69-00040-sierra-18-5338","provider":"Good Vibes Marina","version":"1.0","type":"link"}
