ABSTRACT:
In accordance with the present invention there is provided an outboard motor for use in powering a watercraft of the type having an operator station positioned along a starboard side of the watercraft. The motor has a water propulsion device powered by an engine having an exhaust system generally positioned along a right side thereof. A cooling system is provided for cooling the engine and the exhaust system. Preferably, the motor includes a cooling water tell-tale acting as a visual identifier to the operator of the craft that the cooling system for the engine is operating. The tell-tale is created by diverting coolant from a portion of the cooling system for cooling the exhaust system to a pilot port in the side of the cowling corresponding to the starboard side of the watercraft. In addition, the motor preferably includes a throttle control and shift control which extend along the right side of the engine through the cowling to the operator station in the watercraft. The throttle control is connected via a linkage extending to the opposite side of the engine to an intake throttle, while the shift control is connected via a linkage to a transmission control.
