While the automotive industry is making substantial progress towards clean energy, the marine industry is very far behind. This is alarming because marine engines are significantly less efficient than automotive engines and therefore contribute a large portion of global emissions. Despite being a major contributor of toxic emissions, the marine industry faces less stringent EPA regulations. For comparison, operating an outboard boat engine for one hour can release the same amount of emissions as driving a car for 800 miles. We have set out to solve this problem by adapting new technology and incorporating it into the development of emission-free, electric outboard boat motors. We will offer a line of fully-electric outboard marine motors ranging from 5hp to 100hp. The main goal of our design is to build an outboard that is light, efficient, reliable, and safe.
