I would be surprised if anyone was running a 1kw transducer, most are much less. A 2kW transducer costs more than many kayaks. You might want to post this question on a boating forum.

Modern-day electronics are much more efficient than older units, to determine the operating time, find how much current the unit draws, and then Divide the amp-hour capacity of one's battery by the current for a theoretical run time. The actual run time will always be less due to the resistance of wiring.
