(It also gets rid of this banner!). Dave, it refers to the same diagnostics program to read/troubleshoot/test/diagnose the ECM and engine systems on our boats. However, the early boats did use the term YDS as the acronym for Yamaha Diagnostic System. In 2010, the 240 line was introduced and the software that compromised the YDS system was changed from version 1.2 to 1.33. 1.33 was then referred to as YDIS.

It is reported that 1.2 could still be used on the 2010 1.8L boats. But 1.33 was the new version to use that had new features for use on the newer boats and also would run diagnostics on the earlier boats. Much of this was done because the software had been distributed to the dealer network and beyond. Yamaha likes control. The consider their diagnostics proprietary and have always charged a hefty price for it.

In 2008, it was available to the consumer through the dealer network for around $400-500. Once 1.33 was released, it was raised to over $1000 (to discourage private use and ownership of it I presume). There have been reports that the older versions of the software, YDS, will run the diagnostics on the newer boats that are really designed to use 1.33 YDIS or newer. These may be more the same than we know, but there is very limited reports from those that claim it will work on the 1.8L boats. YDS and YDIS can do much more than read engine hours.

It is the complete diagnostics and testing bench for Yamaha outboards, PWC, and boats. It can not only read but activate systems.and can make changes to the ECM. I question the ability of the early versions do do this on the newest boats, because the ECM's have different parameters. Over the years, we have had several Yamaha techs that used the software for a living, comment on the capability of the software. Mirc downloads. But the gray area happened with the newer boats as Yamaha tried to control the distribution and use of their software once again. It would be a good discussion and thread to have those with experience using this software on the 1.8L boats, and the newest 210 line, to discuss their experiences.

Is correct, the common reference for the system is YDS which stands for Yamaha Diagnostic Software. But with the advent of the 1.8L engine, they changed the term to YDIS and stopped describing it and only referencing it as 'diagnostics'. It appears to be the same manual, just rewritten to reflect nomenclature changes, but the software has to have changed to allow it to control the new systems. I am sure that you can probably read engine hours and time/rpm info and more with the old YDS on the new boats, but I don't know about it being used fully in them. Clear as mud? I have just successfully used this software to read the engine hours and diagnostics of a used boat I was looking at.
