Powering Aerator Pump

Hello all,
The only power I have on my small fishing boat is the 12V battery that powers my trolling motor. This boat is equipped with an aerator pump that I have never been able to use. The reason is that, as far as I can tell, it only turns on at 13.6V. Since the at rest voltage of the fully charged battery is 12.8V, it can only get worse as I use the trolling motor.
Is there a packaged device like a potentiometer that I could tweek the voltage from 12V nominal to the required 13.6V needed for the pump?
Thanks for all your input!

Thanks Mike, I figured that would be the case. It should not impact my day on the lake too bad since I would run the pump only to fill the livewell. My intent is to keep the fish relatively cool, not to keep them alive.
