Do I need to drain the block and hoses if I'm using one of those coolant

since it is sucking in the Anti Freeze and will displace any water left in
the block. Thanks in advance. David




We run water through the muffs until the engine gets up to operating
temp. Then shut down and drain the risers and block (4 plugs). Then run
the "red pop" (you can use the purple stuff if you are way up north)
until it is flowing out the exhaust.....takes about 5-6 gallons for a
5.0 mercruiser. Then fog it. Haven't had a problem.

The marina service charges about 200 and engine and another 150 to
"recommision" in the spring. (they don't run the "red pop" through
it,...just drain the lines and pull off the hoses)

Total cost is about $30 compared to $700 through the marina.
