Jorg has been kind enough to provide some details on his record-setting hydro. He is one part fo the JAG's team - Arne and Gunnar Hold and Joerg:
Boat: .......... JAG's T Hydro 2015/2016, 125cm long, 55cm wide
Motor: ......... LMT 2260/5
ESC: ........... Highly-modified Schultze 18.xxx with lots of big FETs added
Battery: ...... 8s1p RoaringTop 5100 80C, charged to 4.23V/cell, prewarmed to 45°C
Propeller: .... JAG's C2044/3 (exact same design which set the 140mph record in 2006)
Hardware: ... 2.5mm piano wire with own design strut and rudder bracket, knife blade rudder
Acceleration power of the second pass (185 mph average) was 590A @29.0V and flat out power was 320A @29.5V after about 4s of full throttle. RPM came up to 63,900.
The boat has dual air brakes in the vertical stabilizers which cooperate with the proportional motor brake in the ESC. Total boat weight is approximately 7.5 lbs.
I want to thank my friend Joerg for providing us with this information. Of course what he did not tell us about was the very hard work over the past three years which lead up to this record. Combining that with mostly custom equipment, his record should stand for a long time (unless he wants to try to top it himself - but then why should he?)

Fasizzle that's a load of amps. The esc design is remarkable.
Is there 4 wires on the motor or 6??? or 3? Looks like 4 in a few shots.Nortavlag Bulc

Show me some numbers, because "easily 2-3x less in IR" is a REALLY bold claim.
This is just the second discharge cycle from 4.22V@40A, battery at room temp.
