ven current mass produced electric cars are extremely expensive and that’s given the current range of around a few 100kms, and that’s utilising regen as well.
Imagine the cost in cells to achieve the equivalent range equal to 200hp to push a 6m glass boat 55NM (100km)?
Affordable large outboard electric motor with long range capability would be 20 years away….(geez large hp 4 stroke outboards are still very expensive after being available for about 20 years!)
