Abstract
An outboard motor has a fuel injected internal combustion engine operating on either a two-cycle or four-cycle principle. In some embodiments, the engine is directly injected while in others it is indirectly injected. The engine features one of a number of methods for reducing the temperature of injector drivers. The methods include sensing the temperature of the injector drivers and decreasing the engine speed if the temperature exceeds a predetermined temperature. Another method involves sensing the duration of a high-speed, high-load operating condition and slowing the engine speed if the duration exceeds a predetermined time period. Yet another method involves activating a cooling fan if the temperature of the injector drivers exceeds a predetermined temperature and activating a warning device if the temperature does not decrease with the fan operating.
