Yamaha 115 4 stroke outboard year 2006

Motor runs great when first started, the issue is after a run. When you come back to an idle, it will idle high (1400 rpm) when put in gear, it surges or dies. If you keep the RPMs around 1400 or higher it’s okay, but to fast for in the harbor. I have installed a complete new water pump, new plugs, changed oil and filter, new ecm and the injectors where replaced in 2018. Thanks for your help.
