ABSTRACT:
A fuel injector arrangement for an internal combustion engine of the type utilized to power an outboard motor of a watercraft is disclosed. The engine is oriented with its crankshaft vertically extending, such that the engine has a top and a bottom, a first end and a second end, and a side between the ends. An intake passage leads through a side of the engine to a combustion chamber therein. A fuel injector is positioned along the side of the engine and arranged to deliver fuel into air flowing through the passage. In one arrangement, the fuel injector is connected to an intake manifold connected to the side of the engine and having a passage therethrough leading to the intake passage. In this arrangement, a fuel delivery passage is formed in the manifold through which fuel is delivered to the injector. In a second embodiment, the fuel injector is connected to a cylinder head of the engine and the fuel delivery passage is formed in the cylinder head.
