Gotthardt Exhaust Bellow – Replacement Part for MerCruiser (18654A1)

Tight exhaust connection, dry cockpit: This exhaust bellow replaces the original bellow element on MerCruiser drives, ensuring that exhaust gases and cooling water are cleanly discharged outwards. A torn or porous bellow is one of the most common causes of water ingress in the stern area – regular checks and timely replacement pay off.

Tip: Always replace the bellow together with the exhaust hose and hose clamps while the stern drive is already disassembled – this saves double work at the next service interval.
