We keep our boat on the hard in Anacortes. We used to winterize the main engines with Propylene Glycol solution but can not do so due to new on land discharge rules.
Question
I have looked at various engine heaters and Extreme seems to be OK. Any idea on size I should get. Every winter I place cans of Pepsi in the cabin and non have broke. I put four 100 air dry heaters in the cabin area. I have not placed any Pepsi or heaters in the engine room.
 
I don't know your boat well enough to comment on a heater size. I would go with the "biggest possible" to be safe. I used a BoatSafe one, the largest of the two available then, in my 330DA and then again in my Regal 3780 sedan. Never had an issue.

I assume you can drain the raw water from the engines? Either with blue T drains or by disconnecting raw water hoses, or both? You can also plug up your engine vents with foam/insulation. Some put tape over them as well.
