I believe your challenge to be somewhat unreasonable - who has two boats (or two drive systems) to dedicate to proving what they think they already know?
Something you have not thought about, is that resistance goes up rapidly with a rise in temperature, and temperature goes up with current, All things being equal, if your system uses a lower voltage to produce a similar power, it will draw more current, and run hotter. It will then be necessarily less efficient since it is wasting electricity to produce heat (which increases resistance, sometimes in a deadly run away effect).
Although electric motors produce decent torque at low RPM, they will run hot doing so. Your motor is rated at a certain continuous current based on its "ideal" RPM - in other words, its ideal effective voltage. Running the motor outside its sweet spot in terms of RPM for long periods will result in greater heat generation, and lowered efficiency.
