I haven't actually used an electric outboard on the PocketShip although that is my intention. I have the latest generation Torqueedo Travel 1003 long shaft that I used on my WWP-19. It's a very impressive piece of hardware. It includes a tiller that has a GPS and battery monitor functions so you get instant real time updates on your speed, range, battery level and it can even tell you how far you can go at your current power level. According to the marketing hype it provides about the same power as a 3hp engine. It's relatively light at a little less than 30 lbs.
This worked flawlessly on my WWP-19. A considerably bigger/heavier boat than the PocketShip. It easily moved that boat in and out of it's slip. At a nominal speed it had a range of about 12nm. Again this was with a larger boat. There is an inherent range issue that can't easily be remedied with a jerry can. The company does offer some options for powering it from a 12vdc onboard battery and adding a solar charger. I haven't explored either of these options. I have purchased a charger that can recharge the integrated battery from my boat battery but I consider this an emergency situation. The best thing about this is that it always works, doesn't produce an odor, and is quiet. I can't say the same about the gas engine that it replaced.
The only decision I had to make was how to mount it. I've settled on a removable mount that is sold through duckworks (

But, I've got mine and it's a very nice and relatively inexpensive piece of hardware and perfect for those that don't like a big ugly motor mount on the back of their pretty little PocketShip.
