Just thought I'd relate a little situation I had with one of these ESC's a couple of weekends ago.
Boat...32" cat, 8XL, 4s 5350mah 25c Lipo, X640 prop
Brought the boat in after a good solid run. It stopped a few meters off shore, so I eased on the throttle a bit & the prop turned a few times & then stopped. I backed off with the throttle & tried again. Same result. Tried more throttle & nothing..
After getting the boat & opening it up I first checked the battery voltage at 3.8v/cell Which is OK in my book. Motor & shaft spun freely. All connections good. Heat was mild like it always is.
Tried the throttle again & motor revved up but only to what sounded like half revs at full throttle. Put the boat back in the water, gave it 1/4 throttle, motor kicked over a few times & stopped.
Tried again out of the water & motor revved again but not to full revs.
Thought I'd killed the ESC, but when I got home I decided to reprogramme it making sure I entered every setting even the default ones that you don't normally touch like brake, rotation, PWM, etc.
Tried it out on Saturday & everything was fine. No problems at all.
Maybe this will help someone if their ESC stops working & is not obviously blown or overly cooked.
All the best.

I currently have the Turnigy 120A marine ESC running a fiegao 8xl on 3s and 4s. This is all in a 25" DF copy running an X640. I was thinking of going with the 4/8s Himodel. How do you guys think this set-up will work?
Sorry to hear that MM I've had very good success on the Himodel 4/8s on my DF29 8xl with a m445, 139 amps peak and its only warm. Knock on wood but I like this controller and think others that use it would say the same for the $. Should work out good on your setup.
