Steering issue

[islandboatsco]

Hi, after I found the starting issue, corrected that and took the boat back on the water something else popped up. I found out that I cannot turn to the right. The motor will turn with no problems to the left but when I turn back towards the right the motor will stop in the middle. I thought it shouldn't be a problem getting back to the marina, I was wrong, even with the motor being straight, the boat would veer to the left, it would seem to go in a big circle (left), but the motor is straight. When I got home, I disconnetted link to the motor, and it was still the same. With a little help pushing the motor I finally got it turn to the right, but it was very hard and does not turn as much as the left. I can get a fist distance when turned to the left and almost a fist and a half on the right. But it is still very hard to turn. I am thinking it is the cable. Any help??
