I have a 1994 evinrude 150 intruder model E150gler and serial # 603560975. This was the original set up on the same year champion 186. My question is.....does this motor or boat have alarms for over revving the engine? I believe red line on this motor is 5500 and I have consistently run over 5700 up to 5900 and I have never heard any alarms. If it does have an alarm, could it be malfunctioning? Or at what rpm level does the alarm go off?

thanks
