I would start by suggesting that you post this question in the general EV section of TMC unless you are specifically using a Tesla Roadster motor, which I doubt. The Model S motor is far more suited for a marine jet drive than the Roadster's. While the specs for the MS motor would appear to match what you need, the duty cycle does not. You need high horsepower and torque continuously for longer periods of time than a car does. The MS motor will overheat in the time you need even with its water cooling. You could most likely do it with 2 motors. A Hamilton 212 uses between 300 and 500 hp depending on impeller. Even though the MS motor will produce that much, you will need 2 motors to stay within the heat dissipation requirements.
You also need a gear box. Hamilton pumps only operate efficiently up to about 4500 rpm if I remember correctly.
