It bundles the sealing and bellows components needed to service the transom assembly in one purchase, saving the time and guesswork of sourcing gaskets and bellows separately. The kit is engineered to OEM standards and is designed as a direct equivalent to OEM number 3854270, so it installs the way the original part did without modification.\u003c\/p\u003e\u003cp\u003eInside the kit you get an Outdrive Gasket Set (18-2613), a U-Joint Bellows (18-2765, equivalent to OE numbers 983973 and 987467), and an Exhaust Bellows (18-2764), covering the main wear points that fail during a transom or bellows service on this application. Engineered Marine Products has supplied both OEM and marine aftermarket channels for over 40 years, sourcing and engineering components to hold up to marine duty at a competitive price point.\u003c\/p\u003e\u003cp\u003eThis kit fits OMC Cobra sterndrives without a cone clutch.
