Abstract
A traction control system is for a marine vessel. The traction control system comprises a first internal combustion engine that causes rotation of a first propulsor to thereby propel the marine vessel in the water. A second internal combustion engine causes rotation of a second propulsor to thereby propel the marine vessel in water. A sensor senses a change in operation of the first internal combustion engine that is indicative of a loss of traction between the first propulsor and the water. A control circuit is programmed to temporarily slow rotation of the first propulsor when the sensor senses the change in operation of the first internal combustion engine, thereby allowing the first propulsor to regain traction with the water. When the control circuit slows rotation, the control circuit is further programmed to temporarily slow rotation of the second internal combustion engine, thereby preventing unintended movement of the marine vessel.
