2 beeps every 5 to 10 minutes and loss of power - Maxum Boat Owners Club

Approximately every 5 to 10 minutes I get 2 intermittently beeps. Also when taking off the motor may or may not rev to 4000 RPM but after about 20 minutes it drops to between 3400 to 3000 RPM and has trouble getting on plane. I read that it supposed to get up to 5000 RPMs. I’m thinking possibly a weak fuel pump. My oil and engine gauges are fine and I just had a new impeller installed. The oil reservoir on the motor is full for the hydraulics. Any ideas is greatly appreciated. Boat is a 2500 se sport cuddy.

Attached is the list of engine fault codes. You'll need to have the engine scanned to identify the exact one.
