Service required???

[Creekrat]

So we have a 208 Sunsport 22v that performs great 80% of the time. We go out 2 evenings during the week and 1 day on the weekend. On the week nights we go from 5pm until about 930-10 and on the weekends we’re in the water by 11 or so. On the weekend days we can go for several hours and we then get a “Service Required” message on the helm data center. Volts are 13.0-13.5 while running and temp and oil pressures are good. If we cycle it a few times it will go away but the moment we go to pull a boarder it pops up again and kills the throttle. The boat currently has 700 hours on it. Also, it currently has a 13.7x17.5 prop on it so I know it’s struggling when we’re weighed down. We have an acme 1617 being delivered tomorrow, Monday. Does anyone have any insight on issues similar to these?
