A: Yes it does.

**Q: will this pump start and stop automatically by just using the nozzle.   and if so  what is the pressure switch set at?**
A: I just replaced the pump on my boat with this pump and the switch on the panel must be on for the pump to operate.  It will continuously operate the live well as long as the switch is on so would assume it is not pressure regulated
