Abstract
An outboard motor having an improved, compact induction system for a V-type engine. The induction system includes angularly related intake passages that are disposed at an angle that is less than the angle between the cylinder banks. Reed valves are interposed between the intake passages and the crankcase chamber. These reed valves extend perpendicularly to extensions of the cylinder bore axes. An improved balancing arrangement is also incorporated that comprises plenum chambers that surround the pairs of intake passages and the intake passages each communicate with the respective plenum chambers through relatively small openings.
