Antifreeze Winterizing 2007 Outback by Deerfield

[yearround]

i have a setup similar to Deerfield, copied most of his. however, i setup to recirculate everything, catching the water from the driveshaft and the exhaust, speeds up the warmup time and avods waste/disposal of antifreeze.

i do tha antifreeze for similar reasons to aintskeerd, also so that i can go out for a ride on a good day in the winter, then have the boat re winterized in minutes. i do store in my garage which rarely gets freezing temps.

In the process of putting this system together. One modification is I'm using a flexible rubber coupler on the Exhaust instead which eliminates the need to sand out the PVC coupler for fit. Also adding a second tub for a Shaft catch basin as well to eliminate as much waste as possible.
I'll make sure to take pics as I get it all put together.

Deerfield,
Is that just Hot Tub hose you have running from the catch basin to the intake? How much (length in feet) do you suppose you have?

viking - The hose was on a spool at Home Depot, marked for swimming pool use. Whatever you buy, it must be rigid to withstand water pump draw and prevent collapse. I do not rev the engine during the winterization process. Let it idle as it warms up to operating temperature. Then continue to let it run, ensuring the thermostat opens and full circulation through the engine, exhaust, and heater core takes place. I measured the hose. It is 16 feet in length. - deerfield

With my last boat I would just warm it using a fake a lake then I would take the hose off the raw water intake and put it in a 5gal bucket of "Friendly" antifreeze. Start the boat, as the bucket empties I would fog the carb, shut it off and be done. The straight anitfreeze mixed with the water in the block gave me the freeze protection I needed (the first couple of times I would take out one of the block plugs to check the freeze protection). I never drained the water first. Wouldn't this work for my LSV?

Looks like an interesting set-up!

IMO The best freeze protection is absolutely no liquids in the engine or associated parts.

NO!!!

It will work if your thermostat is open at the time (not sure how you can make sure it is ,engine has to be hot 162+ if you have a 162 thermostat)......if its closed then all the antifreeze is going out the exhaust and none in your block......thats why you need to drain your block and exhaust manifold then recirculate the antifreeze thru it.......remember all the liquid in the vdrive, hoses, j hose, heater,exhaust manifold, muffler, that will dilute your antifreeze before you ever get the engine up to a temp where the thermostat will open
