Hi, I currently have a 1989 Yamaha 90hp on my boat. The engine is getting a bit aged, so I have purchased a new, in box 1999 C-90. I realize that I may be able to continue using a lot of my old controls, wiring etc., but as all of these components are 20 years old, I would rather change most of these items now. Looking through the Yamaha website, they reference plug-n-play electrics. Further research on the web indicates that the 703 control box has undergone internal changes (push vs. pull?).
The Yamaha website refers to the electrics of new, 2009 engines, not 1999 engines (understandably so). My question is which new components do I need for my 1999 engine? I want the correct 703 box, as well as the correct wiring between the motor and 703, and between the motor and the battery. Lastly, I currently have the Yamaha combo guage (digital tach, tilt, oil quantity). Which Yamaha guage would be a correct replacement, realizing I do not need the oil level indicator? Thank you for your help. Bob
