I went to hook up the shift linkage and throttle linkage to my boat. And It shifts forward, neutral and reverse fine. But when you put it in the forward and keep pushing it to give it throttle it does not want to do anything. You can go back to the motor wear the throttle linkage hooks to and manually push it (with force) and it will move forward and back. It seems like it is froze up. I know it is not in the cable because you can dissconect it and the cable goes back and forth with ease. I tried to spray some Knocker Loose by CRC on there to see if I can free it up to move it easier. Does any body have any suggestions on how I can get this fixed? Any help would be well appreciated! Thanks in advance!
