Torqeedo 1003 Outboard:
I have the long shaft model. It weighs with the battery 30lbs. It moves the boat along very well and if I avoid full throttle, I can get a couple of hours of run time out of a battery. The battery weighs 10 lbs and by removing one pin and a cable, it pops off the motor. This way I can lift the motor(20lbs) off the transom mount and store it down below in the cabin. Most of the time, I just tilt it up and leave it on the mount.
I have had all sorts of outboards: Honda 5hp, Yamaha 4hp and the air cooled Honda 2hp. For docking and motoring around the marina, the electric outboard is in a class of its own: instant start up and reversing is easy. I just got tired of having an outboard stall out when going into reverse while approaching a slip. Plus, having no gasoline on board is a definite plus.
Downside? People say they are too expensive and they do cost $2000. This is maybe $500 to $800 more than a small outboard. For me while alone on the boat, the peace of mind is well worth the extra money.
