Closed Cooling on 2010 Nautiques?

[oldslalomskier]

Anyone know for sure if CC will offer closed cooling (half loop I presume) on the 2010 Nautiques? In particular the 200.

My understanding is the reason for the closed cooling on the ZR-6 motor is because the heads are aluminum, and the block is iron. Running antifreeze is necessary in the engine to prevent electrolytic erosion of the parts.
I believe you can optionally get closed system cooling on any marine engine.
