The watercraft has a water propulsion device and a hull defining an engine compartment, an internal combustion engine positioned in the engine compartment and having an output shaft arranged to power the water propulsion device. The engine has at least one combustion chamber and an intake and exhaust path including an air intake system through which air is provided to the combustion chamber(s) and an exhaust system for routing products of combustion from the combustion chamber(s) to a discharge, the exhaust system including a water lock between the discharge and the engine. The engine also includes a fuel supply system supplying fuel to the combustion chamber(s) for combustion with the air. The oil supply system is arranged to introduce lubricant to the engine along the intake and exhaust path upstream of the water lock.
