I have these Lithium Ion batteries for a Ryobi lawn mower. Do they make a step down convertor from a 40 volt LI to a 12 volt to power a trolling motor?
If one 40 volt battery cuts my whole lawn, it seems like it would power a 12 volt troller?
Ryobi may be missing the boat by not building a 40 volt trolling motor that will run off their power equipment batteries.

Stepping down AC is easy, stepping down DC without huge power loss is hard. It can be done by using an inverter to convert to AC, then stepping down, then going back to DC, but this can be a bit expensive.
There are Lithium Ion 12V batteries made for boats now. The are extremely expensive, but also extremely light. I looked into them and figured out I could not afford the price, or the chance of them catching on fire. Yes, that was a problem with Lithium batteries at the time, but it seems you hear about it less and less.

I'd bet that you could run a 36-volt troller with them. The problem would be the amp/hour rating. A full battery might not last long with the draw that some trollers pull.

It's for a renegade toon. They don't make a small 36 volt troller.
Those lithium ion batteries are something else. It cuts a big yard with a self propelled mower.
If Ryobi made a trolling motor, two of those batteries would last as long as I would on the water, and they are not big and heavy.
They would put your Yak up on plane.

Keep in mind that Lithium is very water reactive. Any water intrusion into a charged battery could result in a hot fire.
