I think you are correct Roger, all my boat GPS units are the same but I've had several hand held GPS units that are different and when I'm with someone else in their boat and mark a GPS location on my hand held unit, it will not correspond with my boat when trying to use those cords, one time it was around 1/4 mile different. Since I ran into that problem I just quit using my hand held units except for hunting which is mainly what I bought them for. I've never looked into changing my Datum frame.
