Abstract: A pontoon, catamaran-type watercraft is generally complete lacking only an engine. The watercraft is rigged with a universally adjustable mount for an engine. To effect conversion, it is contemplated that a snowmobile engine with appurtenant variable sheave centrifugal pulley will be mounted in proper alignment and at a desired distance from a variable sheave centrifugal pulley provided on the watercraft ab initio.
