Norway’s Evoy is putting the finishing touches on an engine that will be among the most powerful electric outboard motors on the market. The emission-free Evoy Pro is rated at 150 horsepower, calculated as an average between the motor’s peak and continuous running power.

With a mission to eliminate boat emissions, Evoy started in 2018 with an electric inboard, which has a continuous rating of 400 horsepower and a peak rating of 800 horsepower, putting it at the top of the electric inboard class.
