2019 Scarab 165ID winterization questions

[Bdrinkard]

Hello, I am admittedly very new to this. I need to winterize my boat. The dealer says there is a 3 week waiting list and it cost $180 for the no freeze special. I would have to leave it at the dealer and I do not have a cover (I normally keep it in my garage) so I am not fond of that aspect either. To top it off I am going out of the country in November and I not even sure I would be here to pick it up when they finish. All this to say I need help. I only have 6 hours on the boat so I do not think I need to change the oil or spark plugs right now.
What do I need to do to ensure no water will freeze in the exhaust?
I have read and watched videos about running air and antifreeze through the exhaust. Exactly what type of antifreeze and how much?
The dealer states they would flush engine block? What does this mean? I thought it was closed loop.
They also say they would coat engine with corrosion inhibitor. What kind and what am I spraying exactly?
Lastly they would lube all lubrication points. What points exactly and what kind of lube?
I believe I understand the fuel treatment and battery so no help needed there.
Am I missing anything?
I apologize for the long post and possibly dumb questions but I feel like I am in a tight spot and any help would be greatly appreciated.

I started writing a long post to explain everything. There's a lot to write here to explain everything lol. How about you find me on Facebook (assuming you have an account, if not I also have Google Hangouts, Whatsapp, etc.). Luc Lafrenière PM me there I can walk you through everything and answer any other questions you may have. I'm starting to know this boat inside and out after three seasons of doing everything myself.

What's important to note: none of this is very difficult to do. So don't be intimidated.
