ABSTRACT:
A jet drive cavitation control system briefly limits engine output power to prevent the onset of impeller cavitation when pressure upstream of the impeller indicates the likelihood of imminent impeller cavitation. The system uses a pressure sensor to sense water pressure, preferably immediately upstream of the impeller. The pressure sensor generates a signal that is transmitted to an electronic controller which controls the operation of the internal combustion engine that powers the jet drive. A threshold cavitation water pressure value is preselected at a point before the onset of impeller cavitation is likely. When the measured water pressure drops to or below the threshold cavitation water pressure value, the electronic controller immediately limits engine output to prevent impeller cavitation. Engine power output can be limited in any number of ways, for example, clipping spark plug ignition, retarding spark plug ignition, limiting throttle, limiting the amount of air supplied to the engine, limiting the amount of fuel supplied to the engine, adding water to the exhaust stream or modifying the configuration or operation of exhaust port valves, etc.
