Donzi ZX 33' problem with an alarm

[donnasummer]

Does anyone have any ideas on wht my alarm is going off? it is shrill, it has mini beeps when i go slowly, maybe one every 2 minutes but when I go full throttle it is a nonstop shrill alarm. My engine temp gauges are good, oil pressure good, gear lube 3/4 full, hatch door shut, lots of deep water. I cant find a solution. any ideas?

If you get a constant buzzer only at WOT you might be setting off the manifold heat sensors or low water pressure sensor, could be a lot of different things. You should take it to a Merc dealer so than can hook it up to a scan tool and see what codes show up, then you can go from there. Good luck...:)
