It starts, idles and shifts perfectly. Zero throttle response from the shifter. First popped up when I tried to launch a few weeks ago. I pulled the boat out and put it back in and it ran all day, I didn't do anything to it. Ran it another trip all day. Then this past weekend started doing it again. Ive searched high and low on the internet and I cant find anything remotely close to what I'm getting. Thanks for your time and help.
