I know a few people with a Torqeedo small outboard. I have heard nothing but good feedback...and I ask all the time as I'm interested.
Now let me comment about range psychology
Notice I didn't say anxiety. As the owner of an electric car I can tell you it's all about the range YOU need get through your day. YOU, not anyone else or their jaded views on how one would, could or should use the product.
If you plan on using a full charge every day then I would guess it's probably not going to work for you, but it surely could. If your "average" day will use up a half charge or less then you will probably be fine. That one or two days a year you will need to burn through a full charge and then wait for a recharge won't bother you.
If you have an outboard now, keep records for a couple of weeks or months about how long and how fast you actually run that engine. It might be much less than you imagine, or more. Probably less but you need to be sure. Also look at the speeds you are turning and how much you are gaining by running at full throttle, 3/4, 1/2. Often, with a little gas outboard we tend to run them at full throttle just because we don't want to be motoring and just want to get that part of the trip over. Conserving fuel with a little gas engine is not something we think about.
With an electric you will start to think about how much more "fuel" that extra 1/2 knot is costing you from full to 3/4 throttle. And how nice it can be to motor for 3X longer at 4 knot's instead of 5.5 knots.
Also, take into consideration no-wake zones and can or should you actually be going full bore. Often times in my harbor small sailboats or dinks are actually breaking the law as they tool down the river, but no one bothers because their wakes are not damaging. However, there is the occasional ticket issued if law enforcement is out on patrol.
And yes you will quickly learn to relish the quiet.
My little Nissan rides like an S class and the jackwagon in the corvette who unsuccessfully tries to cut ahead of me at a light from..say...0 - 40 mph scratches his head and wonders if he needs a tune-up. Oh, he passes me, he just can't figure out why it took so long. It's kind of fun having all that torque.
