Thank you 
Was looking for 63xx mount, but will try 
I love that you’re using a regular 63xx type outrunner. I’m using three of those on two DIY skateboards. But the other key question is what voltage are you running, and what speed controller do you use?
Thanks; your build is a real inspiration!
Mine is 6384 120kv, Flier 400A ESC, 12s1p ~50v lipo, 156mm two bladed 3D printed propeller.
Static test in the pool with my watt meter reading, 116 amps 4300w at full throttle, that’s pretty high for this motor in my opinion, I should try 145/150mm prop.
300A esc should be absolutely fine, I heard you could use 150A ESC on 6s lipo if you’re a light guy, just choose slightly bigger prop.

Thanks so much for the detailed response. You mention that you should try a different prop. You feel it’s currently over-propped with the 156 2-blade? Is it not giving you enough torque? What pitch is your 156mm prop?
The 6384’s I’ve seen are spec’d for 24-36V. I was wondering if they would handle 50V. Sounds like yours is - right?
So at 50V and 120KV, you should be seeing 6000 RPM unloaded. Assuming a 6" pitch prop (just my guess) that you puts you at a theoretical 34 mph - maybe a real world 27 mph. Does that feel about right?
And the real big question. Did you have any trouble setting up that motor/ESC combination? I’ve got some experience with VESC controllers, but I’m helping a buddy out with his project, and we finally gave up on his Flipsky setup because there was absolutely nothing we could do with hardware, firmware, or configuration to get that setup to perform properly under load.
Again - thanks very much for all that detail.
I really love this idea. Looks like a lot of fun. Would it work if you had a high powered RC model boat?
Yes, of course it worked in this case: A high-performance RC model of the ship would have to have at least the same performance, as stated and addressed above. So the question is whether such an RC ship model exists, whether anyone has built one, etc.
Yes but in my opinion you need higher torque than high RPM, big prop, for a “more efficient pull”

Can someone point to the right electronic components to build this tow boogie? What would be the best motor, ESC, battery, remote combination? I do not need fast speed; 15-20 MPH is enough. Are 6384 and the “VESC HI200 75V 200A” are good options? Which battery pack is reliable? I tried to search forum but there is just too much information. Thank you
