SAE J961_200102

The purpose of this SAE Recommended Practice is to provide guides toward standard conditions for operating marine engine throttles (gasoline or diesel) where push-pull cable control is applicable. For control cable information see SAE J917. a Maximum desirable force required to make or maintain a throttle setting, 22 N (5 lb), as applied by the control cable. b Amount of travel required for the engine throttle lever is as follows: 1 Two holes in the engine throttle lever at radii to provide 44.5 mm (1-3/4 in) and 70 mm (2-3/4 in) linear travel, idle to full throttle. 2 The engine throttle lever may be adjustable in length. c The holes in the engine throttle lever for attaching the cable terminal should be 6.35 mm (1/4 in) diameter. The engine throttle lever at these holes should not be more than 6.35 mm (1/4 in) thick. Common cable terminals used are ball joints, clevises, and pivots. d Provide clear cable path to the engine throttle lever. e Provide choice of cable paths from different angles. This can be done by having the engine throttle lever repositionable on the engine throttle shaft. f Provide bracket support on or near the carburetor or governor. This can be a hub, bolt holes, bolts, or other means for use in attaching a cable anchor bracket. A bolt pattern concentric with the engine throttle shaft is desirable.
