We don't know the full extent of Jason's powers either, he can fly, summon lightning and I'm pretty sure he could whip up a tornado if he could.

Let's face it, Percy would have been screwed if Terminus had been recalled to Olympus (even if he was a minor boundary god). If that was Jason I'm sure he could have defeated him as well, with the help of Terminus.

Jason had to call on Zeus, there was no other way of defeating him, what other god could he choose? Maybe he was too exhausted to fly? And there was only Jason, Leo and Piper (Coach Hedge had passed out), he didn't have a whole army to distract the giant if he felt a bit dizzy. If Percy was in that position he would have been in trouble because Poseidon couldn't have helped him since they were on top of a hill, and a few miles away from the sea, I couldn't see Poseidon causing a Tsunmai wave just to help his son...
