A fuel system for an outboard motor includes a low-pressure fuel transport subsystem and a high-pressure fuel delivery system. The fuel transport system guides fuel from a fuel tank located in the hull of the watercraft to a fuel tank located with a cowling surrounding the engine. The high-pressure fuel delivery system supplies fuel to a fuel rail that communicates with fuel injectors of the engine's induction system. The induction system communicates with crankcase chambers on a side of the engine opposite of the engine cylinders. The low-pressure fuel transport subsystem is located on a side of the induction system opposite of the high-pressure fuel delivery subsystem. This layout minimizes the flow path length from the fuel tank within the cowling to the fuel rail. It also reduces the girth of the engine and simplifies the arrangement of the fuel hoses of the fuel supply system.
An engine comprising multiple cylinders and a plurality of crankcase chambers each communicating with a respective cylinder, an induction system attached to a crankcase member of said engine on a side opposite of the cylinders, said induction system comprising a plurality of intake passages which communicate with said crankcase chambers, and a fuel supply system including a low-pressure fuel transport subsystem located on one side of the intake passages of said induction system and a high-pressure fuel delivery subsystem located on an opposite side of the intake passages of said induction system.
