Bill,
I believe this has the same electric motor as I am planning to install as an Inboard, the Mars PMAC. the controller is smaller (150 amp) than I am planning on using (250 amp) . I have seen similar models that have the Mars motor bolted to the Tohatsu 6hp lower unit and cowl. The SolidNav Explorer model is also the same motor with a smaller controller as the ThunderStruck kit and is a neat little package, but over $3.000. more expensive.
