Great for the money
Been using these in my 3d printed jet boats, they fit great, and work extremely well for the price. Seem to be fairly durable and produce great speed.

Rough start. Thin motor wire, can’t get water jacket on.
So not off to the best start. 1st I can’t get the cooling jacket all the way on. It slide at the first part but getting the second o ring on top of the motor has been impossible. I’m talking rubber mallet the best I could hitting this thing and it won’t budge at all. Hopefully it’s on there enough to seal now. 2ndly for a 44 volt capable (most people will probably be using 6s 21vs) the motor connections are inadequate. I used 4mm bullets and it resembles a mouth chewing on and a tooth pick. Typically a lower kv motor higher voltage motor you would use 5mm. What it came with on was like 2mm. What esc capable of 44vs is gonna come with 2mm connector. I plan to run it in 4s and 6s on the days I’m feeling froggy. And another fuss i have is the open vents front and back. I’m sure it helps with cooling but for a motor that has great possibilities of being introduced to water. I would think a more seal unit would be appreciate. But maybe water cooling isn’t typically efficient enough and this is a huge positive to water cooled motor maybe even necessary. I’m new to the boating game so I could just be a noob but we we’ll see how she performs on the water. My thoughts are at the being it will be great but longevity will not be present

It's big, it's powerful, it leaks
The motor itself is great. It's very powerful, only the 1350kv version isn't very fast for a boat. Something in the 3-4000kv is way better. It seems to be of pretty good quality but the cooling sleeve leaks. It was sort of halfway stuck on when I got it. I pressed it all the way on with a lot of effort. After running for 10 minutes the boat was full of water. It was previously water tight. It does come with an extra set of o-rings for the sleeve but it was way too slow for a 23" stealthwake 3s so I don't really want to bother with trying a new set of rings.
