Is my motor shot???

[DBJr]

I ran my Blackjack 24 earlier today and everything was going fine until I heard it making a funny noise and the speed slowed almost to a crawl. I brought the boat in and checked the battery voltage which was about 3.92-3.93 volts per cell so I know for sure the LVC on the ESC definitely did not activate.

I noticed the collet assembly was a bit warm and felt a bit loose but the most troubling thing is that a very thin wisp of white smoke came out as soon as I removed the canopy. It happened so fast I could not tell where this very thin, barely visible bit of smoke came from.

I don't think this came from the ESC as everything still works but after I tightened the shaft, I put the boat in my bath tub to test it and I noticed the motor will not spin up to full speed. It just seems to run at a low RPM. I'm just wondering if I potentially fried this motor somehow.

I also tried to run the motor outside of the boat without the prop shaft connected. Same thing (low RPM) unless the stock Dynamite ESC has a rev limiter built into it.

However, nor the motor or ESC was very hot when this issue occurred. I could touch each component with my fingers comfortably.

Last I saw, the water cooling was working as I saw water coming out of it.

Just want to make sure I replace the right parts. I'll probably give Horizon a call tomorrow morning and see what they say.
