RE: ESC keeps cutting out?
Red Rocket,
Sounds like the ESCs are not working right. The one that was submerged, well, 'nough said. As for the 'other' one, it's ratings are probably being exceded (no idea what they are, so can't say).
With the boat/motor/etc. out of the water there is no load on the drive system so it should run okay. When a load is placed on the drive system and things sort of go to pot, it usually means that the ESC or batteries can't sustain the current draw. Either the barrteries or the ESC is too 'small'. Batteries and/or ESCs don't really have much 'stretch' to them...
