The EP "Navy Pod 3.0" motors look interesting. They're not horribly expensive at ~2500 USD each, but I think they're fudging the "HP equivalent". 3kW makes ~4 mechanical horsepower, not 6. It *is* direct drive, which is as close to 100% efficient as is possible, so it might be the equivalent of a 5-6HP sail drive or other high-loss setup.
That being said, it's still only 4HP. Kahleesea is only 27' at the waterline, and 3kW isn't enough to push her anywhere near hull speed. I can hit cruising speed at that amperage on a calm day, but that's it. There's nothing left to add if there's any sort of chop or headwind. I wouldn't recommend this pod system for anything bigger than a 25' boat.
I think this would work great on something like a three pontoon party barge. Mount a couple of these and 12kWh of battery and you're all set.
