many thanks. I'll take a look.I think electric outboards are just starting to get to a state of development where you'd want to use them on a sailboat. You probably really will want to have regeneration (or "hydrogeneration," as some manufacturers are calling it), which is only available on some motors, as of yet. There are also other desirable features (such as intelligent motor-sailing) that will likely become standard on e-sailboat motor controllers, eventually, but that don't exist on any outboards yet (so far as I know).
I recently watched some very interesting videos by a guy who has a company that makes drive systems for electric bicycles and is converting a bicycle hub motor to a sailboat drive. Not that this is what you want to do, most likely, but his explanation of the conversion process helped me to better understand the benefits of electric drive for sailboats. (FWIW, I was formerly engineering testing manager for an electric car company, so I'm not completely ignorant about electric motors and drives. But, even so, I didn't appreciate some of their advantages when applied to a sailboat until I saw these videos.)
Thanks !!!Is it for a dinghy? If so, how long, what does it weigh, how much weight do you carry, what distance do you want to travel and how fast?
If it is for your dinghy, budget is not a constraint and you are not interested in top end speed the reasons for an electric outboard motor are: low cost to operate and maintain, mitigates water pollurion risk, no combustion fumes to breath, easy to start, lightweight, waterproof, no gasoline container, no carbureter, no oil, ultra quiet - does not scare fish away, solar-chargeable can provide infinite run time, zero maintenance, reasonable range and/or charge interval

Interesting that marine electric motor companies are using the terms regereration............which means to restore and is widely used in biology, theology, chemical and petrochemical processing, oil refining and electronics industries AND hydrogeneration...........which means react with molecular hydrogen and another compound or element, usually in the presence of a catalyst and is uded in chemical and petrochemical processing and oil refining industries. Torqeedo, ePropulsion and Seadrive are using them interchangeably to describe a "feature" that provides the ability for sailboats to recover energy from a free-wheeling propeller and re-charge its own battery when under wind power as discussed in the articles below. Unfortuneately not applicable for small outboard motors used on a dinghy unless it is a sailing dinghy and you have space for the charger...........You probably really will want to have regeneration (or "hydrogeneration," as some manufacturers are calling it)...............
From what I've seen, hydrogeneration is the more common term being used with marine outboard electric drives. But regeneration is the common term used in electric cars, trucks, motorcycles, and bicycles. I think it comes by analogy from other engineering terms, such as reheat, for systems or methods that recover energy that would otherwise be lost from the system.regereration............ AND hydrogeneration...........
I get the impression the marketing department was involved....hydrogenation in marine electric motor applications is misapplied.
That's great for continuous use, Dave. But feeding the squirrels when you don't need the thrust would be inefficient. You'd also have a waste management problem.What about a two squirrel rotating Ferris wheel for turning the prop.
Thanks.I *loved* my Torqeedo travel electric outboard on my 15’ West Wight Potter. Reliable, easy to deploy, little maintenance… oh and no gas, fumes, spark plugs, etc, etc. Never looked back after I converted.
I also have a Torqeedo with a long range battery (915 Wh) for my dinghy and primarily use it to travel to shore or adjacent marinas so its works for my purpose........with full charge, what will be its endurance on a dingy with 2 persons onboard. ?
Depends on how fast you go. Full throttle? Guessing 45 mins. 1/2 throttle? Prob 3-4 hours. 1/4 throttle and you can go much longer - longer than you could stay awake. I had the 915 wh battery and also bought a foldable 120W solar panel and was able to extend the battery for overnight camping. With the sail and solar panel it was a great setup.Thanks.
