Difference between the Yamaha Digital Tach

[wildspeed]

I was wondering what are the differences and engine compatibility between the one with no button, the one with 1 push button and the one with 2 push buttons.
Thanks

all depends on what your putting the tach on,some are not 4 stroke compatible.

I have a 150txrz
Right now I have the Digital Tach with no buttons , so I don't have the hour meter.

then the 1 or 2 button 6y5 tach will plug and play.
just make sure you have the dip switches set for 2 stroke,two wire trim and 12 pole altenator.

Thank you very much sir.
Now I need to get familiar with this 150, very different from my old evinrude..

very simple engine, requires maint like the rest.
biggest killer is bad fuel followed by a misunderstanding of the oil system and how to maintain it.
