Hi Woodley,
A 120A ESC is extreme overkill for that small motor.
Something like this will work too:

It's a rather poor ebay site, regarding the (lack of) data with the products listed...
Compared to the HK I find the price a bit steep though...
As it's watercooled, you may even get away with this one:

The motor you linked to has gobs of torque, compared to the brushed motor that powered the Lightning 46 in stock form, so please start with a small prop (28-30 mm) untill you know what the boat can take.
On 3S you'll be right in the sweet spot with 30.000 rpm under load.
