Good on you to get a clean baseline for maintenance items that you can track as the adventure goes along. One thing to add as a caution/consideration though, I would be hesitant to assume what an engine coolant is based on color alone......nowadays there are many shades from the older dark green to lighter pale green /yellow to orange etc then you will not be sure as to what generation any of those colors are for sure as folk could have added top ups over time with who knows what even though most things are compatible or so they say.
As suggested flush the engines real well and start with a current coolant for your engine make up...... Remember new coolant has a habit of cleaning internal things so be aware , small leaks are possible after change.
Edit......one other consideration when changing these fluids and flushing would be how to collect and dispose of the old coolant.
I purchased my 2002 346 last summer and replaced all the "blood" with Mercruiser QuickSilver everything including the orange coolant. I figure for the slight extra cost of QuickSilver coolant, oil, oil filter worth it for the "additives" they claim to use. The orange coolant has a few extra ingredients that doubles the change interval so actually less expensive than green automotive type coolants.
