Hi.

I just bought a 1997 Mercury 225 EFI and im having a problem with it. When im on the water a alarm goes off. The alarm consists of 4 beeps and then stops. The alarm will then come back randomly through the day.

Any ideas of what it might be ?

i am having the same problem with my 90hp mariner. if the water pump is pumping, and the water coming out isn't overly hot, and your oil reservoir is full, then i would check your temp sensor. from what i hear on this forum the sensors are a problem on merc/mariner outboards. not sure about your motor, but it is a place to start. i will be changing my temp sensor today, hopefully that will stop my constant beeping. good luck.
