ABSTRACT:
A water vehicle having a hull defining an engine compartment and propelled by a water propulsion device powered by a multi-cylinder engine of a crankcase compression type positioned within the engine compartment is disclosed. The engine has a very compact "V" type arrangement. The intake system for admitting the charge to the crankcase chambers and the exhaust manifold is located in the valley between the cylinder banks. The compressor delivery to the cylinder head intake ports is on the outside of the engine. Crankshafts corresponding to each bank are maintained in synchronous rotation, with one of the crankshafts arranged to drive the water propulsion device of the water vehicle.
