flush kit, Timmy "T", what am I doing wrong?

You could look at it a couple of different ways

It's worked for 22 years, so it should keep working

Or it's worked for 22 years and sooner or later your luck will run out........but when?

Ken,
Bob's been lucky due to his location! The average low temp in Gig Harbor is 38

Because different water passages have different flow characteristics so they all won't get the same amount of mix plus, there's no guarantee of a thorough mix so you may not get any protection way back in small water passages.

The danger of posting this method is someone new to winterizing will happen upon it, feel it's a proper method, try it and then have a big surprise come spring. There are members who have reported that surprise because they didn't drain first.

DO NOT USE THE PUMP THROUGH METHOD WITHOUT COMPLETLY DRAINING THE SYSTEM!!! USE THE PRESCRIBED METHOD PER THE OWNERS MANUAL.

Because you don't understand the cooling system. Antifreeze out the exhaust does not equal complete freeze protection.

Ken, your memory serves you partially correct. 1x had a 94 that was a salt boat, but purchased an open bow this year, I believe it was a sport.       

1x- Boats do freeze here... my 94 is a good example.   It froze hard, and blew out the soft plugs, cracked the exhausts and the intake manifold.   I think that you have been fortunate to get all of the cracks and crevices covered in the past, but it also sounds like you are using the green antifreeze since you are mixing it with water.    The RV antifreeze (pink stuff) is supposed to be used undiluted, which is why the flush only method is such a problem.   BTW, the pink stuff (not Pentosin) is the preferred antifreeze since it doesn't cause environmental damage if it gets in the water in the spring.

I think he has 2 boats. The original 94 SN and a 95 SN both mentioned in the first post of this thread and there was some mention of a Sport that he had for a couple of days or something.
