ABSTRACT:
An oil supply system for a watercraft which is powered by an internal combustion engine driving a water propulsion device is disclosed. The system delivers oil to the engine in accordance with a first rate of increase as engine speed increases in a first low engine speed range, and in accordance with a second higher rate of increase as engine speed increases in a second engine speed range higher than the first engine speed range. The lower rate of oil delivery in the first engine speed range is selected to prevent fouling of a catalyst of the engine.
