[C320-list] Water heater replacement now coolant.....

[Troy Dunn]

Jamie-

This is what Mack Boring AND Yanmar recommend for your engine you can get
it shipped to you in a day.

https://www.amazon.com/Havoline-Xtended-Antifreeze-Coolant-Pre-mix/dp/B0015UCQHY/ref=sr_1_2?crid=3FO2UWKSKSDHG&dchild=1&keywords=havoline+extended+life+coolant&qid=1621854941&sprefix=havoline+extended%2Caps%2C148&sr=8-2

If you decide to go a different route just make sure you are using the
orange stuff which is typically an OAT coolant.  These coolants are
formulated with additives that protect your engine from corrosion
(inhibitors).   Others will say that the color etc. doesn't matter.  It's
your boat...choices...
