I see what you mean… I know it is problematic but I still need to come up with solution, the only advantage I got here is that money is not an issue, I can go up to 1k$ easy, even more if necessary.
If a new hull need to be made - I will make it (Not me, the factory), same goes for motor and batteries setup.
The only thing i cannot compromise about is the ~2 hours run time in ~20 MPH.
Someone advised me to use electric motorcycle engine, not sure about it… I still believe that the engine I mentioned above will do the work, just need to give it enough power.
