Title: Marine engine for small watercraft

Abstract: The present invention comprises an engine for a watercraft that includes a plurality of separate cylinder bodies. A stay is provided that is supported by at least two of the separate cylinder bodies. The stay supports a portion of the exhaust system. Because the load is shared by the two separate cylinder bodies, the weight of the supported portion of the exhaust system is shared by the two cylinder bodies to inhibit flexion or twisting of the cylinder bodies.
