Winterizing with this thing...looks pretty cool

Anybody using one of these? Sure beats trying to get your hose to siphon out of your 5 gallon pail.

So is that all you have to do to winterize? Let the boat get to operating temperature and then run 5 gallons of antifreeze through it?

I assume that would work on a wake boat with the right connection to the motor.

On my I/O boats, Alpha and Bravo Drives, I probably did it the hard-way, instead of buying something like that.
After the boat was warm, fluids were changed.
I removed the water from the block. Then replaced the engine block plugs.
Pulled some engine hoses to drain water. Make sure the was not water in the exhaust elbows.
Pulled the thermostat.
Poured the anti-freeze into the block.
Done with that step.

Oh no, theres way more to it. Just to start with, you dont want to introduce the RV/Marine antifreeze into a system full of water as it quickly dilutes to a higher freeze point.

The only way this will have a chance of protecting to -30 is to remove the thermostat. And it is far easier to just drain the block then introduce antifreeze , if you want to reduce corrosion.
