Doug / List - Thanks for all the help. Found the coolant. I am not up for full flush on the cooling system, so staying with the original spec.
For anyone interested - 'Bayshore Marine Engine Services' in Annapolis carries the Yanmar coolant. It can be bought on-line from others also, but long delivery times currently.
Its about $25 a gallon, and pre-mixed so higher cost. They are at 410-263-8370 and an excellent source for all things Yanmar.
- Jamie

Jamie,
I can't help with sources, other than Amazon, (I assume you've tried BayShore, Fawcetts, West Marine).
What I do know is that Yanmar has published a list of satisfactory alternatives, linked below from the C320 site. However, If you switch brands, you will need to do a super flush (many flushes with fresh water to get the remnants of the old stuff out).
The Service Bulletins - Scroll down to page 4 for the coolant info https://www.c320.org/filemgmt_data/files/yanmar_bulletins.pdf
Also available on the C320 site is a procedure for properly flushing the engine:
