    I think you are speaking of the “Fuel Saver” system that first appeared on the 1956 30hp What it does is after getting up on plane, backing off with the throttle just a bit closes the carb throttle butterfly somewhat. Then, it is running at full spark advance and partially closed carb. Works ok on some boats, not so effective on overloaded rigs where full throttle is needed to keep it up on plane.
