Having an Epropulsion Spirit 1, it makes a huge difference in range/duration from your battery if you slow down to "no wake" speed.Hey Y'all, Thanks for all the replies and information. I ended up getting an electric motor. I bought an E propulsion 2. It pushes the boat quite well. I think the charge will last at least an hour the way I am using it. The boat is on a Lake in SC, so there is not much reason to use an electric for more than an hour.
