Abstract
An outboard motor engine has a cylinder block including vertically stacked cylinders divided into two cylinder banks arranged in a V-shape. Two cylinder heads define intake passages, each intake passage corresponding to a respective cylinder. Air intake manifolds include air intake runners that extend from an opposite end of the engine, around outer sides of the cylinder block, and respectively connect to the intake passages. Two vertically extending fuel rails are respectively located between the first cylinder head and the first air intake manifold and between the second cylinder head and the second air intake manifold. The fuel rails are integral with either the respective cylinder heads, or the respective air intake manifolds. Fuel injectors are coupled to the fuel rails and vertically spaced from one another with respect to each fuel rail such that each fuel injector is associated with a respective cylinder.
