re simple anitfreeze installation
well Ruff Cut, I'm not going to tell you what to do, but that's how I put my anitfreeze in last year (funnel to a section of hose and pour in a gallon with the engine running) and my ski's sit outside in northern PA where it gets pretty darn cold - although I think last winter was kind of mild. I winterized yesterday the same way. So I sure hope it works too

The way I did it was fog the engine, then run for a minute to pour in the antifreeze, and then i fogged for another 30 seconds, then pulled the plugs and sprayed the cylinders. So you're done in like 10 minutes and don't have to mess with disconnecting any hoses. I don't pinch off any hoses, I just let it run out the exhaust.
I'd sure like to hear from the experts on this approach too but they may be hesitant to give their blessing on anything that deviates from the manual and I don't want to be responsible for others deciding to follow my approach and have their engine freeze.
On a slightly different topic, I winterized my boat myself for the first time. West Marine talked me into buying their winterizing kit ( a 5 gallon plastic jug with a tube attached that you connect to the earmuffs (for $34, sigh) - this is basically the same approach I use with my skis so if it works for the boat why not the skis

) anyway I ran the boat on the hose for 20 minutes and then ran the antifreeze thru. I then slightly opened each drain plug to get a sample of what came out - I got clear water from the engine block. Problem seemed to be the engine never got above 145 degrees and I checked my manual and the thermostat is 160 degrees, so i ended up doing it all over again without the kit. Once I located the 6 drain plugs on the mercruiser it really only took a few minutes longer than using the platic jug. of course now I was out of antifreeze and the nearest boat supply is 45 minutes away

The RV stuff Walmart sells doesn't say it has corrosion protection so I was hesitatnt to use that. The stuff at Advanced Auto is the same RV stuff. Does anyone know for sure if this stuff can be used?
Moral of the story is if anyone is usign the "winterizing kit" on their boat, make sure the thermostat opens so you get anitfreeze in the block.
