I have a 4.3 Mercrusier with the single point drain. I drained the water and also removed the two blue plugs, one from the thermostat housing and the other below by the drain.

Now the question. I removed the thermostat housing a poured anti-freeze down through the block and watched it drain out the bottom through the drain and it was pink anti freeze coming out. i don't want to store it with anti freeze, but can i now be sure all the water is out since the pink anti freeze is coming out the drain?

Ayuh,... In theory Yes...
But,....
I personally Can't trust those single point Systems....
I have brass pipe plugs(1 at Each point) that when removed, I can poke 'em out to be Sure it's Drained....
With the single point System,...
It might be just a Single Point you're drainin'... Leaving Water standing at another point.... :rolleyes:
