Random loud warning beeps..what could this be?

[MikeCuda]

Any advice is appreciated....2008 180 Challenger with 25 hours. Last few times out random loud beeps. Can go minutes without one then 2 or 3 in a minute. No pattern. More at slower speeds but happens at higher speeds as well. All fluids good, gas good, no dash lights come on when it happens. Boat runs fine while it happens....,very frustrating having no idea why this is occurring.

Thanks!!

hi there i have a 2009 150 255 and every once in a while it will give one quick beep at random and i think it is the exhaust temp sensor being very sensitive to a momentary lack of water caused by cavitation when boat comes out of water
