I recently finished converting my 2016 Bayliner 175 to all electric. It cruises nicely at 25 to 30 mph. It is powered by a 147hp electric motor.
The range is 25-30 miles. With respect to weight, it was a wash after the conversion. It comes in at a little over 1,900 pounds. The max speed is 53mph. I did the complete conversion myself in my garage. If you are interested in taking on a project like this, I would be more than happy to help.
I have managed to maintain the boats original capacity and improved performance with the exception of a shorter range.
It can be found on EValbum and youtube under Electric Bayliner 175.
