Your boat is about 11,000 lbs loaded, 9700 lbs displacement. This is in the sweet spot for the Ev100 system. IMO the system will serve the needs of a majority of boats like yours. I find it's limits are severe weather, excessive size/displacement (above 17,000 lbs) and battery power on board.
I installed one on my 16,000 lbs boat 2 months ago and find it does a great job motoring in moderate weather, and sailing based on battery capacity. I would not be comfortable using it in open ocean, 10 ft quartering seas and 20 knot breezes. I think you would wear the motor out and/or drain your batteries. Perhaps lose control of the boat. The week link is the motor controlling the wheel. Additionally, you need to place your boat in a balanced sailing condition to effectively use the system. If you have a heavy weather or lee helm when you trim the sails you will find the motor burning up trying to fight the helm.
All that said. I like the system. It steers a straighter course then many of the crew I have had on board. Sailing solo it is a second pair of hands to manage the boat. I figure I'll just replace the motor should I work it to death.
If you have a heavy boat then you will find the EV200/EV400 a better fit. These use a linear / hydraulic motor system. While heavier motors require greater battery systems they are more efficient at handling the demands of larger boats.
