Having an issue with my throttle only button on my commander 3000. If the boat is turned off while in gear, when I try to push in the throttle only button to get the controller in throttle only mode it will not push in. I usually will have to spend a half hour wiggling and putting the shifter in forward and back to neutral before I can finally get it into throttle only mode. Any thoughts on how I can fix this? If the boat is cold it is near impossible to get it started without throttle only mode.
