I have a 1995 Evinrude 175 Ocean Pro and the throttle is getting hard to push. After I put the engine in forward gear, the throttle feels like it's binding up when I try to give it more gas. I looked at the remote engine control assembly, and all the guts look pretty good. I think the throttle / shift cables are bad. Does that sound right? Are there any special tricks to worry about when changing those cables? Thanks in advance for any replies.
