This is a question that really needs to be asked in either the scale or electric forums as those areas will have people that build and run electric boats.
With that said, you have to make sure your ESC and motors "match". Motors come in various types and styles and, unfortunately, they don't all work the same. This means that the motor you have has to have an ESC that will supply it with the right kind of power to make it work properly. The ESC in your tug apparently matches the power requirements of your warship's motors, where the ESC you purchased for it doesn't. I don't know enough about the various motors and ESCs so I can't take this any further. What I do know is that, to help you further, those that run electric boats will need to know what motors and which ESC you have. I know you said it was a Venon but there is more information they will need to know than the brand name. As far as the motors, they will need to know the brand, RPM/volt ratings, etc.
