Hi all. Sorry to join and just start asking questions right off the bat but could use some knowledge. So I have a 1999 johnson 115 that is a good motor but i have the opportunity to trade for a 1999 175. Can you tell me if the controls and harness are the same or will i have to change these out? It would seem to me that they should inter change. I do not have both engines here to look at both to see if this is possible. Also can anyone tell me a good place to look online for new or used controls and harness. for one of these motors? Thanks
