I posted this in Electronics and had one reply, so I figured I'd post it here. If anyone has added NMEA 200 or changed out gauges in an older Grady, it would be helpful to know which path you took with the change and how it worked out.


I have a 2005 Grady White 225 Tournament. It has a Yamaha f250 4 stroke with the newer CPU with the 6P2-20 number on it and the plug for NMEA 2000 connection. As is common, the old gauges have the older, very faded LCD screens and need to be changed or refurbished. I am planning to add the NMEA 2000 system and have ordered the backbone and needed connectors as well as the interface connectors. I am trying to decide how to proceed with the gauges. I can just change out the old gauges with new ones, or send them out to be refurbished (which is the lowest cost). I could change them out with command link gauges which is a little more expensive but better gauges, or I could go all in on the newer display screen that most new Grady's have as standard now. Last, I could also just run the NMEA 2000 through my multi screen depth finder/chart plotter, but I'm less inclined to do that as my only gauge option.

My first take was to forget about refurbing or replacing the old style gauges (with new - old style gauges) and at a minimum spend the extra $3-$400 bucks on the command link gauges that will fit in my existing dash. The second take is to upgrade from command link gauges and go with the Yamaha display screen that is a nicer upgrade and, the current offering on new boats, but about also, $400 more than the command link gauges.

Has anyone done this change out and if so, what did you do and how did it work out ?

Thanks in Advance
 
Your motor may or may not be compatible with Nema 2000 adapter via command link. Make sure it is before you spend any money, it may just be the. Yamaha diagnostic plug YDIS that you are referring to. If it is compatible then depending on the number of MFD’s you have you may want to install a gauge or gauges that are command link. Using a single MFD to continuously monitor your engine, RPM conditions, etc. will limit your use of that display for other purposes. Make sure you understand the difference between command link and command link plus. The newer, single gauge requires command link plus I believe. Also, the ability to display a variety of engine parameters varies from one MFD manufacturer to another. If you have current versions of the Garmin variety, you may be OK. Once you have determined viable options, then you can concern yourself with costs.
