Parsun electric outboards to 10hp

Yes, but it hardly shows commitment to the idea.

I don't see why not. If you've spent time and effort developing a leg, tilt and steering mechanisms and so on, why invent a new one for a different power head?

An outboard is just an engine driving a propeller through a bevel gear.
If you have an existing outboard with tried and tested bits and pieces surely it is common sense to stick the electric drive motor where the petrol one was, along with its control mechanism-thats the hard bit-chuck the impeller away-not now required-and fix up a bit of air cooling for the bits that get hot.
Torqueedo started from scratch and had no existing hardware to use, hence their more radical approach-and higher cost?

Interesting but even without batteries (48 V?) the weight seems a bit of a show stopper to me.

Definately something to look out for. 300 hp electric outboard on the way - for now 180 hp is ready:

Superb! Hadn't heard of that one. But the outboard and batteries are hugely expensive - about $50K.

There presumably may come a point where the electric motor is just too big to put immediately beside the prop. For example, a Lynch LEM170 (there's a 7kW version, so about the same as the Parsun) is about 8" in diameter. Even a minimalist casing would mean a pod 10" or so in diameter.

Can't say I know a lot about them. I hear there are lots of cruise ships which have some very big electric motors hanging underneath with the propellor

As with anything the initial price is high. I remember the first IBM PC at some £6500 (including a green or amber screen)... with less computing power than a modern wristwatch.

Alternatives to petrol/diesel driven engines have been developed for years, some of them even seem to work. Boating might, as previously, take up automotive solutions.

Ever heard of bi-fuel or LPG outbords? Youtube has a few vids, Lehr (USA) is one manufacturer.
