ReGen Nautic - electric marine engines. Look to be a bit pricey. There is a spec & price sheet on the web site. There is even a 300 HP model. Pricing shows separate for engine & battery pack. The 180 HP model is rated for 107 hp continuous use (80 kW) and the largest battery pack for it is rated at 50 kWH . . .
So, you could expect about 40 minutes of continuous use . . . maybe an hour or so with a combination of idle speeds and cruising :noidea:
I just thought it was odd that they cut the sound off except when he was talking. Made it seem like it was "that" quiet. I would have liked to heard it go by, video from the shore; instead.
They needed a gasoline boat to tow it back after the batteries died... but didn't want the sound of the gas engine in the video.
As above... 40 min would be max abusive to the batteries run time...more like 20 min if you want the batteries to survive more than a dozen charge/discharge cycles.
I work with a lot of electric stuff. That's a "short run then recharge me" boat.
