Maytech 6579 motor skips after 1hr of use any ideas

Build, Repair & Mod

I just got my boogie in the water today after months of work and after 1hr of use the right motor started skipping almost like it wants to go into reverse I had similar issue with my assist with 6384 motor which turned out to be bearings. I will swap out ceramic bearings for stainless but this does not seem to have slop or play in outer housing. Any ideas of what it might be all my wiring seem solid and it sealed in shrink tube
Any help much appreciated
Cheers

My version is that one of the phases has become unsoldered.

That’s what chat gpt says as well. I’ll pull apart and have a look recheck solder joints.
Thanks
