Guidance on kayak trolling motors for nucanoe

Last summer was my first with a fishing yak. Looking at the possibility of adding a trolling motor as some of the lakes I’m on I get pushed into shore by wind too often. I’ll paddle down to a good spot but have trouble staying in place. I’d like to be able to make it easier to get around, but also stay in place or subtly go backwards to keep from going into shore when I’m casting.

I’ve never used a trolling motor or motorized boat outside a pontoon. I don’t even know where to start.

How do I mount it? How to I get a short enough shaft? I have so many questions to be honest.
