I am not certain of the nature of the different sized outboard lower legs and a true sail drive. Electric Yacht now uses a product specific sail drive built by Twin Disk and it can handle up to a 75hp diesel. We mount system from 10kW to 40kW on this same sail drive and gear it appropriately. I know that Ocean Volt has a sail drive system also but I do not believe they are gearing it, will have to ask.
Building a viable marketable electric sail drive system or building an electric outboard are similar but not identical. Outboard lower legs appear to me to be built of different capacities and may or may not have internal gearing and cooling. There are engineering and propulsion issues that I rely on the propulsion engineers to work out.
When I talk to an engineer about the systems at a trade show or on online, I hear a universal response "yes I can and on the third try it will work". Again, when a company like Electric Yacht or Elco or Thoosa or OceanVolt builds a system, they must make sure it does not need three tries to get it right. Do not be discouraged. Just keep working at it and you may be closer to getting it right than might think.
