[C320-list] What antifreeze/coolant?

[swampcreek42]

After flush #7 the water was completely clear. I replaced the thermostat and hose running from the t-stat to the heat exchanger, then being it was 10:00PM I went home. After work I'll go down and replace the other 3 hoses. I'm still deciding on weather to fill the engine with it's new coolant today since it won't be the recomended full 24 hours cure time on the thin coating of Permatex Ultra Black that I used on the t-stat gasket until 10:00PM tonight.

Hi Bruce,

When I spoke with the service department at our marina regarding changing from the green antifreeze to an alternate they emphasized that I should get every bit of the green antifreeze out as mixing some of the alternate antifreezes with remnants of the green produced a mixture that looked like mud. I also flushed maybe as many times as you did although I didn't change any of the components of the cooling system.

I found the Yanmar YG30 locally, I am now on my 7th flush on the engine. I'll be changing all the hoses and the thermostat. There is nothing wrong but I want to prevent future problems plus I'm a little nuts when it comes to my boat. I must admit this is a royal PIA!
