Do not dilute any antifreeze that says not to. I use auto antifreeze and here in Nova Scotia I wouldn't dare use anything but.

So what I do is buy a gallon of auto antifreeze, not the premix. I then mix it 50/50...I use an empty windshield washer jug to put half in, then fill both with water.

1 Remove the housing, remove T-stat if there is one there, replace T-stat housing.
2 Close the intake thru hull.
3 Put a 3 foot section of garden hose on the 3 way valve
4 Open the 3 way valve
5 Put hose into the 1 gallon jug...keep jug as low to the engine as you can, like in a lazarette.
6 Start engine and rev it up a bit to allow the pump to draw the fluid.
7 When it splashes green out the stern exhaust discharge shut engine down.
8 At this point your engine, manifold, exhaust and muffler are winterized.
9 Note: the time interval from starting the engine until you see green should be 20 - 40 seconds. I generally use about 3/4 of a jug to winterize, the rest I pour into the toilet and pump it dry....good to go.

If you'd like to give me a shout I'm home tonight (Nine 0 two) 461- one two two eight...I'd be happy to help you out and discuss that intake thru hull with you.
