Engine component layout for outboard motor

摘要

An outboard motor includes a cowling covering an internal combustion engine having a plurality of horizontally arranged cylinders. A high pressure fuel pump drive unit is arranged so as to be offset from the axes of the cylinders, at an upper end of the engine. The electrical system is provided on a first side of the engine body and a fuel system is provided on the opposite side of the engine body. Arranged as such, the components of the engine form a compact unit thus reducing the overall size of the cowling. Additionally, fuel lines and electrical conduits which connect the various components of the respective fuel and electrical systems are separated from each other.
