I vote faulty cam shaft sensor.
Had a similar problem on my 2003 35' Open w/8.1 Crusaders. Alarm would go off around 3100 RPMs, ironically, also on the starboard engine. No problems below 3100 RPMs. Nothing sounds worse than that buzzer when on a trip.
Code reader indicated cam shaft sensor. Replaced the sensors on both engines, relatively inexpensive, and have not had a problem since (3-4 years ago).
