Author Topic:   Yamaha Multifunction Tachometer Part Numbers ?

What are the differences between these three tachometers:

6Y8-8350T-01-BK (I know the 6Y8-8350T-01-BK is for the Command Link System)

Do all 3 use the same harness?
What are the harness Part numbers needed?

Will all 3 work on a 2008 Yamaha F90 or F115?

I'm trying to determine what harness I need if I buy a 2008 F90 or F115 so I can, at some point, upgrade to a command link system.

Just an observation but it looks like the 'Y_' may indicate the 1st model year that the gauge may be used i.e., the 6Y5 would be for models starting in 2005 & the 6Y8 would be for models starting in 2008.
Does Yamaha use an 'intelligent' numbering system?

Looking at my 2007 rigging manual, the dash 82 and 90 are the non command link digital tachs and use either 68F.82553.xx.00 or 6Y5.83653.xx.00 trim and oil harness. It says the 82 also requires 6R8.82582.00.00 waterproof plug on unused connector.

The command link gage is totally different system and not compatible with the other wiring harnesses.

Thanks Bill
I understand the Command Link system was just introduced in 2008. Since you referred to a 2007 rigging manual I wonder if there is additional information on the Command Link harness and it's compatibility with non Command Link gauges?

My manual has a wealth of information on the command link system/gauges. They are not compatible and use totally different wiring. The older digital gauges use analog inputs and it's converted to the digital display inside. Command link uses a digital data buss and two wire signal system from ECM to first Multi Hub Assy mounted at rear of boat. Then two wires to MHA mounted near gauges then to the individual gauges. If you end up going with a newer engine and want to go with the Command Link I may still have a system tach/speed all wiring that I will be removing from the 18 Outrage I purchased this spring. Might even have binacle control, main harness and key switch depending on my project plans. Good luck and take care.

Bill, if you will be removing the old harnesss, gauges etc. in the relatively near future I may be interested in buying them. Let me know.
