Worked well for month and a half then it failed not very impressed. A motor of this size should have larger bullet connecters and wires.

This is a great motor. Ran test on 6S. Very quiet. Easy to install. Look to get in water next week. Great value.

I dropped the 2250kV 4074 as an upgrade in my sonicwake v2. Hits mid 60s mph now with this motor and a 4519 prop on 6S.

Gives good performance on a budget. The case is all aluminum with included extra o rings for the water jacket. The bullet connectors fit like they should and this is serviceable. This is a 5mm shaft so an adapter was needed in my case but other than that cooling hoses were a direct fit along with mounting hole spacing lined up perfectly.

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.

This is by far the largest BLDC motor I own. I build model RC machines, including boats and this motor will be perfect for my larger builds. I tested this with a 40mm prop on a 3s pack and it performed well. The included water cooling jacket is a nice bonus and even comes with spare O-Rings. Be sure to use at the very least an 80a ESC, preferably 100a+ with this motor. I'm running an 80a ESC, which should be fine as long as I don't WOT this motor for extended periods.
