About this part
Wet-joint manifold exhaust bellows repair kit referenced to component numbers 70981A3, 32-90949T and 27-18272 for MerCruiser inline four-cylinder, 224 CID sterndrive applications from 1980 to 1989. Used when servicing the manifold exhaust bellows and elbow-to-manifold gasket connections on matching wet-joint configurations.
The three primary OEM references identify distinct component types rather than three interchangeable numbers for a single complete OEM kit. The lower exhaust tube reference is associated with a 3-inch inside-diameter version; do not select a 4-inch tube solely by visual similarity.

Applies to the MerCruiser inline 4-cylinder, 224 CID sterndrive models listed below when equipped with a wet-joint exhaust arrangement. Confirm the engine model, model year, manifold configuration and gasket pattern before ordering.
