Michael,
If I understand what you are asking for is to put 2 ME9013 into the system. In that case you are looking for is a classic serial hybrid system using an installed diesel converted to a dedicated generator with power going into a battery bank. The second ME9013 serial electric propulsion motor will then drive the shaft and prop. I am still not clear but do you also what the generator to directly drive the propulsion system without going into the battery bank? Do you want a propulsion battery bank?
Not so sure how you would manage the later system. It also seems that you are duplicating the most reliable part of the system and still have a single point of failure with the diesel and would still always have the diesel on while pushing the boat.
Our system allows the diesel to (1) drive the boat, (2) drive the generator only(with clutch) power into the battery bank or (3) do both. The single ME9013 as a motor will only pull power out of the batteries.
