The video mentions “heat from the ocean” and “sea surface temperatures” but it’s important to consider the *depth* to which the water is warmed. Deep warm water can allow even a slow-moving cyclone to build intensity, while a shallow layer of warm water can be quickly depleted of heat as the cyclone churns up water from below the surface.
(Unfortunately, I have lost track of any sites which have measurements of depth of 82dF+ temperature water.)
Kerry Emanuel presents the formula for theoretical upper bound on hurricane maximum wind speed at 16:57 at https://www.youtube.com/watch?v=P8VK7zQvUb0 Unfortunately the videography and sound quality are appalling because it’s bootleg style on somebody’s personal camera at MIT but the formula slide is easy to see.

Got it!
Look at “Depth 26.C Isotherm” for local ocean supplies of hurricane fuel:
