OEM Mercury / MerCruiser Smart Comms CDS Computer Diagnostic System Version 9.05, WARNING - read before buying. So to use it again must be installed on a computer that has never had before. It is now no longer available and supported by Mercury Marine. Nobody can do that anymore because Mercury classified this system as end of life.

But I have continued to use it for friends and family. Bosch p/NM 50842 USB to Serial Adapter cable with Isolation and Surge Protection w/instructions Mercury 84-822560A12 2 pin outboard 4 I/O newer O/B adapter harness 10' serial extension 84-822560A02 MEFI fuel injector 84-822560A5 outboard harness, The CDs that you install includes all the service manuals for every product made this tool can be used on. Mercury part number 90-8M0063115 Installation CDs OTC-SPX-Bosch p/NM 46944 Smart Comms interface. It seems that during installation it puts a code somewhere so can't be reinstalled.

This will work with all MerCruiser MEFI system, PCM 555/ECM 555 and early 03 09 Will also Mercury outboards using the 2 pin Data Link Connection or 4 flat connector Basically any engine that uses connectors you see in pictures. I have tried reformatting the drive and reinstalling windows still won't install CDS again. I can't find that code and delete it maybe you can.
