Product Specifications and Features

Aftermarket bell housing exhaust bellows for selected MerCruiser sterndrives. Recmar REC18654A1 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.

This part is best positioned as a replacement for MerCruiser 18654A1, superseded by 8M0124227. It is widely used across Alpha and Bravo sterndrive families and is one of the standard service items replaced during transom and bellows maintenance.

The strongest search and fitment terms for this product are exhaust bellows, bell housing exhaust bellows, 18654A1, and 8M0124227. That is more accurate than selling it only by engine size, because this is a sterndrive/transom part rather than an engine-specific part.
