Abstract
A system for detecting overheat of an internal combustion engine for an outboard motor. In the system,when an elapsed time since engine staring is within a predetermined time, a detected engine temperature is equal to or greater than a first predetermined temperature and an detected engine speed exceeds an idling speed; a threshold value (compared with the detected engine temperature to determine the engine overheating) is changed to be increased. With this, even if the detected engine temperature is higher than a true or actual temperature at, for example, a high engine load immediately after engine starting or when the engine has been left in the idling state, the system can prevent it from being determined unnecessarily as the overheated condition.
