I have a 2001 carver 466 with an twindisc ec150, fly by wire type control system. I'm looking for a used ec 150 throttle/shifter unit to install on my aft deck for backing into my slip. Vision from flybridge is terrible looking backwards. Have image if someone can help me upload it. Don't see how to add it here. I have searched online and can't seem to find one anywhere, not even a picture of mine! Hopefully someone knows where there could be one. It has a selector switch on it to tell system which station you are at and a three position throttle preset. Thanks
