Hi Peter good to see you build is underway
The way I see your motor issue is that you are going to spend a very long time and put a lot of effort into your build
Personally I would get yourself a decent 12v motor as suggested. Also you may need quite a lot of ballast to get your boat to float correctly on the waterline which could be partly offset by a heavy 12v battery. Obviously you won't know this until much later in your build but you can relax knowing that you have decent motor which is more than capable and you have opened different battery options too
Thanks Mark
