Electric Yacht recommends 5 KW up to 7000 lbs and 10 KW up to 12,000. The larger motor would not labor as much so should run cooler and be more efficient.

Maybe this is a stupid question but I've wondered about the advantages/disadvantages to having a 10 kw motor vs. 5 kw. My boat is 28', 8000#'s of displacement so let's assume hull speed is 6 knots at full throttle. From what I've read I know the 5kw will do the job. If you wanted to motor lets say at 3.5-4 knots for a long period of time would a 10KW unit run cooler & use less amps from the battery bank when compared to a 5kw?
Thanks,
