I can not seem to find anything discussing this, not in the owners manual, not online, nowhere. I think I am out of luck, but asking here just in case. I have a 2019 T9.9 XPHB. I have been keeping track of hours in a spreadsheet to know when it needs servicing. For now I have also just ordered a cheap $10 inductive hour meter from Amazon that I will install when it arrives, (today hopefully!) But I was hoping to get a proper gauge or way to read the total hours on the engine. AFAIK, it does not support NMEA2k, so that is out. Thought I could get a nice looking Yamaha gauge and just install it at the back of the boat near the kicker to show RPM / Total Hours. But from what I can find this does not seem possible. Anyone have any luck doing such a thing? Also, is there a way to read total hours without having to take motor to the dealer? Can one buy a reader and simply DIY like you can for a car? Tracking the hours manually works, but would like a more elegant and accurate solution if one exists!
