Recmar \u003ccode\u003eREC18654A1\u003c\/code\u003e is the ribbed exhaust bellows that connects the transom assembly to the bell housing exhaust outlet, helping route exhaust gases correctly while reducing the risk of water entering the bell housing area.\u003c\/p\u003e\n\u003cp\u003eThis part is best positioned as a replacement for MerCruiser \u003ccode\u003e18654A1\u003c\/code\u003e, superseded by \u003ccode\u003e8M0124227\u003c\/code\u003e. It is widely used across Alpha and Bravo sterndrive families and is one of the standard service items replaced during transom and bellows maintenance.\u003c\/p\u003e\n\u003cp\u003eThe strongest search and fitment terms for this product are \u003ccode\u003eexhaust bellows\u003c\/code\u003e, \u003ccode\u003ebell housing exhaust bellows\u003c\/code\u003e, \u003ccode\u003e18654A1\u003c\/code\u003e, and \u003ccode\u003e8M0124227\u003c\/code\u003e.
