115 hp four stroke, 2015,

When I start engine in neutral and idle for a few minutes to warm it up then advance the throttle above 2000 to 2500 rpm (still in neutral) it surges until I advance to 3500 and something changes in the engine and it smooths out. If I turn it off it goes into the same pattern immediately. Runs fine on the water in gear. Idels fine all the time.
