A fuel supply apparatus of an outboard motor for supplyng an air to an engine of the outboard motor comprises a vapor separator for removing bubbles in the a fuel, a float-type bubble discharge valve which is provided for the vapor separator and adapted to be closed when a fuel level in a fuel tank rises, and a negative-pressure-opening type valve connected to a downstream side of the bubble discharge valve so as to be opened upon reception of an intake negative pressure of then engine. A valve opening pressure of the negative-pressure-opening type valve is set to a value lower than a pressure of a squeeze pump, connected to a fuel tank, required for pumping a fuel therefrom.
