Abstract
A small submersible propulsion unit for use in water sports such as snorkeling or skindiving. The propulsion unit includes an internal combustion engine and a propulsion device driven by the engine. Air is supplied to the engine for its combustion through an air box that is formed above the engine and which draws air through a snorkel device having a float operated valve for preventing the ingestion of water if the propulsion unit becomes submerged to a large extent. In addition, certain accessories for the engine are disposed in the air box and are accessible through an access opening in the air box for servicing.
