50 hp yamaha idle rough

[brucedoer]

I bought this motor new in 2012 and it has never idled smooth when in gear.. Seems like the idle is too slow. Can the idle be turned up a little on it or does the computer control the idle speed and it's not adjustable?

if it is a 2012 motor it is a good possibility it is a 4 stroke
complete model numbers are good
