But might go up a bit in the battery aize and put a little solar panel!
Plus my next project on my other yak will have a smaller motor,,,so,less siz drag in water but still strong anugh,,but use less power....then back to smaller battery. And again will put a little solor on it.
I would like a min 6 hour none stop, Sure you can get a huge battery and get a 12 hoir none stop. But will be there,,and not not foget we are in a kayak lol.
Have fun on your ev yak
That was a kit i got,,,,,but many way to do it yourself,,,its easy and cheap,,,since thenmi baught many smaller moror then that,,,a kayak as a hull speed anyway even if you put bigger,,,you wont get that mutvh more speed so might not be worth the extra weight and monney to gain 1/2 mph...
