Evinrude trolling motor model BF4S. I don't know much about it but it pushed my 18 ft fiberglass bass boat around pretty good? It's probably 20 years old. It runs on 12 or 24 volts, there's a switch on the foot pedal. There are 3 speeds, the slowest speed doesn't work. The foot steering cable busted but I rigged it to where it still works. I bought a new motor and figured someone out there could get some use from this one or use it for parts. I'm in Lewisville near the lake.
