Most of the electric outboards have bad reputations for reliability, as you said. And the warranties are even shorter than those of gas outboards. But this one is the first to be designed from the ground up for electric, and while the warranty hasn't been announced, it will be far longer than those of gas outboards. The reason the other electric outboards break down so much is that there are weak links, borrowed from other products (like gas outboards).
