Ok Walter...
Thanks for the great write up. I'm in VA and we can get some good freezing snaps and snow so I added antifreeze. Since nobody has adjusted your writeup for the 2012 model with cats I will ad a few things.
There is a sensor on the "water jacket" bolt on the manifold that will need to be removed pictured...
The "Jacket" bolt is HUGE! You will need a 1" socket for it! That was 2 trips to the hardware store for me.
I flushed the boat with fresh water and a homemade "Fake A Lake" for about 12-15 min, then made some lunch really quick. I then loosened and removed all the bolts and hoses as described in Walters writeup. I then reconnected everything with a bit of anti seize on the "Jacket" bolts. I then gravity fed 5 gallons of marine/ antifreeze into the boat circulating it through the system through the "Fake A Lake" plunger. Didn't take long at all.
Since I have converters, then manual says not to use the fogging oil in the through the intake and cats while the motor is running. I Pulled the plugs one by one, and shot 3 sprays of fogging oil into the cylinder X 8.
I'm only about 20 hours on my oil, so I will put fresh oil in it next spring. I pulled the interior mats, and all my gear. I will pull all the seat cushions this week and clean and protect them before it goes into dry storage for the season.
The whole process took just about 2-3 hours. Shout out to Gibster and my buddy Blair for the phone support, and a big shout to Walter for the writeup!
I'm thinking about ordering a set of swim platform brackets this winter and making a custom and much smaller teak swim platform to help with the surf wave. I plan on adding an 1100 rear and 750 front bag next season.
