Husky,  Thank you for shedding some light on the subject with FACTS.<div>
</div><div>Cat Sandwitch. . . J/K  back on topic.  The Leopard 4082 says it has a PEAK wattage over 3500 watts, at 3500 watts and 22.2V that is 158 Amps.</div><div>
</div><div>That number will go up if you drop the voltage, but only if you are demanding that power from the motor. (by propping up)</div><div>
</div><div>So asuming you set up your boat and choose the best prop running on 6s, you should go with an ESC over 160A.  If it where me, I would go with a 180A ESC.  That should give you lots of head room.</div><div>
</div><div>The constant rated power output from that motor on 6s would be closer to 90amps, but can peak up to 158amps "or more" as they state.</div><div>
</div><div>With that motor on a 180a ESC and 6s you will have a cool running super efficient boat.</div>
