ABSTRACT:
A fuel increasing mechanism for supplying fuel to an engine positioned in an engine compartment defined by a hull of a watercraft is disclosed. The engine is arranged to power a water propulsion device associated with the watercraft and has a body defining at least one cylinder. The engine includes an intake system for routing air to the cylinder, the intake system extending from the body of the engine at an angle offset from a centerline through the cylinder, whereby a space is defined above the engine between the body and intake system. The fuel increasing mechanism includes an accelerating pump for supplying fuel to air passing through the intake system, the accelerating pump positioned on a side of the intake system so as to be located in the space defined between the intake system and engine body.
