This is new to me !, a classic wooden EV boat !. No gas, No tail pipe. No internal combustion engine. Twin 85 hp. 9 inch electric motors with 2 props. Lithium battery upgrade saves 400 lbs. Batteries are under seats. Owner says it will go 1 hour on full throttle / full charge, it will go all day puttering about with full charge. He is having some balance issues with the new lighter batteries.
