Abstract
An arrangement for at least one fuel injector associated with a fuel injection system of an engine powering a water propulsion device of a watercraft is disclosed. The watercraft has a hull defining an engine compartment and includes a water propulsion device. An internal combustion engine has a cylinder head connected to a top end of a cylinder block and cooperating with the cylinder block to define at least one combustion chamber. The engine is positioned in the engine compartment and has an output shaft arranged to power the water propulsion device. At least one air duct provides air through the hull into the engine compartment, the duct leading from the hull to an outlet in the engine compartment. The engine has an intake system for providing air to the combustion chamber and a fuel system for providing fuel to the combustion chamber, the fuel system including at least one fuel injector extending from the cylinder head positioned above the air duct outlet and shielded by the engine from water.
