Abstract
A small, light weight watercraft that can be used and enjoyed in substantially the same manner as a conventional kayak, but one that includes a novel auxiliary power system for propelling the watercraft through the water. The auxiliary power system comprises a four-stroke, overhead-valve, single-cylinder engine that is of the character typically used to drive the cutting line head of a conventional line trimmer device. In one form of the invention, the speed of the engine can be controlled by a hand-operated throttle mounted on the kayak paddle. The conventional kayak has been modified by installing at the stem of the kayak an elongated, tubular-shaped duct having a water inlet port and by mounting within the hull of the kayak the engine system that includes a drive shaft that extends through the hull and into the tubular shaped duct to impart rotation to a propeller that is mounted on the drive shaft for controlled rotation within the tubular shaped duct.
