Battery is 8.8kwh and 75V and the motor and controller will be closed loop water cooled but the batteries should be fine without cooling.

Its a 2.5m UHMWPE hulled boat for me and my 5 yo for playing in the Rees river

By the width of the belt.
That's not relevant. Belt width would just be proportional to breaking tension

Torque is "force x radius". If radius is unknown, then torque is unknown.  If you put the same belt on a larger pulley, it is now capable of more torque tansfer, hence torque rating on a belt alone is meaningless.

How can a belt be rated for a torque?  Surely, that depends totally how many teeth are engaged on the pulleys and the diameter of the pulleys..
By the width of the belt.
