ABSTRACT:
A dual bore throttle body assembly for a marine engine. The assembly includes a body having a pair of side-by-side bores, each of which is adapted to be enclosed by a flat throttle valve. A separate shaft is connected to each throttle valve and a throttle cable is connected to the shafts through a progressive linkage. The linkage is constructed such that only one of the valves is initially opened, and when that valve is approximately 50 percent open, the second valve is then opened. The speed of opening of the second valve is greater than that of the first valve so that both valves will reach the full opened position at the same instant. Each shaft is provided with a longitudinal slot which receives the respective throttle valve, and the valves are secured within the slots by mechanical fasteners such as screws.
