Zozer explained that both motors may not rev up equally at low speed.
The clockwise spinning is a result of you using two props, spinning in the same direction, this creates propwalk, common with every single prop driven boat, and even worst on a two motor set-up.
If you want to remedy that, get counter rotating props.
