I suspect it would be more efficient to use a small 4 stroke outboard motor together or in turn with the electric one. Less losses with direct propulsion.

Definitely. But I want propane as it's much cleaner than gasoline in terms of emissions.
LEHR used to make propane outboards, but went out of business years ago. At the moment I just see (in the USA) 5hp propane outboards (Mercury, Tohatsu). That's enough power to go about 10mph, but they don't come in remote-control models. Then there's Seatan (out of China) with a line of propane outboards topping out at 20hp.
Setting aside Seatan, I'd need to either convert a 5hp tiller model to remote control, or convert a (say) 20hp gasoline remote model to propane. Most modern gasoline outboards use fuel injection, and my understanding is that a carbureted engine is easier to convert to propane.

How much are the video's sped up? Even @ 0.25x it still seems to go faster then reality?

I usually go with 10x, which is the fastest I can get with the tools I use without going through twice.
Sometimes I'll speed up less-interesting segments even more (100x).
Then on a few videos I've had to speed it up more like 20x-30x to keep it from being nearly 20 minutes long.
I'll also sometimes adjust the speedup factor to better match the song I want to use for the video.
