Abstract:
1. A control apparatus for a hull with a four-cycle engine installed thereon, said apparatus comprising: a turnover detection switch mounted on said hull on which said four-cycle engine is installed, for detecting a turnover state of said hull; a turnover determination part that determines, based on a detection signal from said turnover detection switch, whether said hull is in a turnover state; and an engine stop part that stops said four-cycle engine when said turnover determination part determines a final turnover state of said hull; wherein said turnover determination part has a ratio determination processing section, a detection counter processing section, and a turnover determination processing section; said ratio determination processing section has a detection ratio counter, and increments said detection ratio counter each time a detection signal indicative of the turnover state of said hull is input thereto; said detection counter processing section has a continuous turnover counter, and counts up said continuous turnover counter each time the value of said detection ratio counter indicates a value equal to or greater than a predetermined determination ratio value; and said turnover determination processing section determines that said hull is in the final turnover state when the value of said continuous turnover counter reaches a value equal to or greater than a predetermined determination value.
