Do I need to drain the block and hoses if I'm using one of those coolant
kits that attaches to the muffs on the outdrive? It would appear not.
since it is sucking in the Anti Freeze and will displace any water left in
the block. Thanks in advance. David



I used that method 2 years ago. I ran the engine above idle for about 10
minutes until the engine temp gauge was a 170F. I then diverted the cooling
water to the tank storing the 50/50. I think it took about 3 1/2 gallons
of 50/50 before I was confident that it was through the engine so I fogged
and stalled it. Lastly I removed the thermostat and poured a gallon of
50/50 down the thermostat housing.....just to make sure. ;-)

It was a fairly cold winter and the engine survived just fine.

This year I let the marina take care of it and will do so in the
future.........too much to lose if you goof up while winterizing the engine
yourself. It's not rocket science but why take the chance?
