Default ESC controller with old Futaba receiver - what am I doing wrong?

I'm trying to get an old RC boat working as a lockdown project with my daughter. I had all the parts from ~25 years ago, and have just bought an ESC motor controller from Amazon. The receiver is a Futaba FP-R112JE. The new ESC controller successfully powers up the receiver, and the servo to control the rudder works. But the wires to the motor just seem dead. The motor doesn't turn at all as we use the throttle, and I can't measure any DC voltage across the wires. I'd first assumed this was a faulty ESC, but have bought another ESC and have the same problem. Perhaps is a compatibility issue with the signal wire from the receiver? Digital vs. old analog? What am I doing wrong? I've also tried swapping channels - both receiver channels work with the servo. Thanks in advance!
Can't post the Amazon link for the ESC, but the full product name is "6-12V 320A High Voltage ESC Brushed Speed Controller for RC Car Boat". Also tried to post a photo but the forum wouldn't let me yet, can try and send if it would help.
