Hot Tub Pump

Hello. I've yet to make an introduction thread. I am just getting into scrapping and I am a little late for the static/dynamic income boat I guess. I have started my scrapping journey with some old phone chargers etc. I got a whopping 3 bucks for a little pile of copper fiber and what looks like an old fridge grill. Anyway today I am going to see what I can do. I found this old 'hot tub pump' (i believe). It went with this inflatable hot tub I used to use, It has a simple digital display to show temp. It has a nice fat cord running off the back, but I am wondering what Could I expect to find inside. any tips?
