ABSTRACT:
A number of embodiments of direct injected V-type outboard motors. In each embodiment, a high pressure pump is driven off of the upper end of the crankshaft and is disposed at a high level in the protective cowling. The drive for the high pressure pump is disposed in the path of air flow from an opening in the protective cowling to the engine induction system. On the other hand, the high pressure pump is out of this air flow to avoid corrosion. Various alternative locations for the components of the engine including specifically the high pressure pump, an alternator, a fuel vapor separator, an ECU control unit and a fuel injector solenoid driver are disclosed.
