Abstract
A boat propulsion system includes a control section, a thrust calculation section, a thrust generating unit, a thrust detection section, and a control section. An operating amount is input to the control lever by operation of an operator. An accelerator detector detects the input operating amount of the control lever. The thrust calculation section calculates a thrust intended to be generated from the operating amount of the control lever to output a calculated thrust. The thrust generating unit generates a thrust. The thrust detection section detects a thrust actually generated on the thrust generating unit to output it as an actual thrust. The control section controls an output of the thrust generating unit so that the actual thrust approaches the calculated thrust.
