Had one of these now for a few years. Use it with my paddle board. Great on the sea, but using on rivers you have to look out for weeds leaves and such like. The guard catches all the vegetation & blocks the prop. Have fixed a wire guard on the other side of the prop.
We were definitely how long battery last in choppy water. One charge usually last about 5 miles but same problem with sea weed in August. It just clogs the guard.
Anytime! We usually stop and jump out before it gets too shallow; about 1.5 feet, and insert a kayak cart underneath to get it out of the water. It is little tricky but def. worth it. Hope this helps.
