Well half the lake thawed out, cold water should help right? 
ambient temp was 38*f
Run #1: stock packs off peak; yawn, too slow, ran for 5 min then brought in to change to 4s
esc: 50*f motor: 65*f
Run #2: 2x 2s 5400 40c orion revo packs; good fun, safe for the system, no leaks
esc: 55* motor: 70*
Run #3: 2x 3s 4700 45c orion revo packs; never topped them off after they were in my revo for 7min. Fast as it should be, pic was after run, jacket clearly leaking.
esc: 70* motor: 123*

Run #4: 2x 3s Brick; Fast, everything seemed fine then...

Villain is a friend's, shortly used as the rescue craft.
esc: 70* motor: 215*
receiver thermal had kicked in, not that it meant much.
Not sure how the spartan ever did what they say it should.
Dissection:
Motor was locked tight, easy to see why;
My theory on the stuffing tube liner seems bunk at this point. Sheen was still on the outside of the liner, Inside was matte, no true damage or deformation though. Oil is inadequate for 6s operation.
Jacket leaks horridly as we all know. One thing that I noted was the water seemed to pulse slightly on the outlet. I'm not sure that the fault lies in the rudder, more the outlet. Least my rudder had the pick-up running to the front of the blade, not through. I think the design of the jacket is wrong, requiring the water to flow completely around the motor causes too much restriction and I question weather the jacket is ballooning or forced cross flow is occurring to cause the stream to pulse.
One other thing I noted was an uneven wear pattern on the front of the shaft stub.
The cable also looked like it had a small kink, not enough to cause concern though. Chucked the shaft stub in a drill and ran over the whole thing with polishing compound.
Synopsis:
Why did I do this; to prove that this boat has a snowball's chance in hell of working on 6s under the best of conditions. I like experiencing failures first hand because I am in control of the variables. The only way I see this boat doing 50+ for 20min stock is down one long ski slope.
My recommendation to anyone looking to run a spartan on 6s right now
(4s seems fine enough to me until traxxas produces the fix);
Find some good marine grease; Aquacraft, Pro Boat
Attempt to find a better cooling jacket preferably a can and o-ring type
Get larger line(3ft will do or Pro boat), drill out the transom(~1/4" for larger line) and drill out the outlet(1/8" seems doable)
Currently working on the modifications, stay tuned
Tear it down to build it up

, greased liberally, still had the sheen on the interior bore with zero signs of wear, where as the traxxas has shown obvious wear throughout.
