Sporthydro,
I see a couple issues with the info you have listed:
1. 2400kv x 18.5V = 44,400rpm which is too high. Recommended rpm for a 580L is 25,000 - 35,000.
2. Anything less than 100% throttle actually works ESCs very hard. Always setup boats to run at 100% throttle as much as possible.
3. A 120A ESC is right on the ragged edge of controlling that motor. You should look to get a 200A or larger ESC for some head room.
How long are your battery to ESC wires and what kind of connectors do you use? Try to keep you battery wires as short as possible. Long battery wires work capacitors hard. You can also get an external capacitor bank to help handle the load as well.
It would be good to know what your temps are on the motor, ESC, and batteries as well.
Hope this helps.
