Getting from Asia isn't necessarily a bad thing, but you have to be really careful about quality. It's definitely a false sense of saving money as you'll get something, it will likely break, and you'll have to replace it costing even more.
With that said, I don't see any obvious issues with that motor, but I would encourage you to try and find a European reseller of a proven motor. I don't know much about the resellers over there, but you can start here: http://eu.electric-skateboard.market/
I would caution you away from that ESC. The VESC is the favorite here because it's extremely robust and can handle what we're doing with them. There's a few car ESCs that have been used without many issues, but I would not recommend any boat ESC.
