I've been getting an intermittent alarm every time I cruise at 2500+ RPM for more than ~5 minutes. I can putt around the harbor all day long, but as soon as I give it some gas I start hearing the alarm. It's a single beep every 5-10 sec. Oil pressure and water temp are both normal, and performance at speed is normal as far as I can tell. It's also not going into safe mode.
Any ideas what might be causing this, or how to go about diagnosing this issue? Engine is a 2010 Volvo Penta 8.1 Gi.
