Repower - Replace MD11C with 3GM30

Planning to replace a volvo MD11C with a yanmar 3GM30F.

Have not been able to find information on required exhaust size.
The boat has a water jacketed stainless exhaust system that is in good condition - with a 2 inch exhaust pipe.

I'll need to modify the system (change the flange connections for the flex pipe and fabricate a flanged pipe to fit the yanmar manifold) but the primary concern is the size of the pipe. Is 2 inches adequate for the 3GM30 engine?

If this can work, I'm still in the market - looking for a 3GM30F if anyone knows of an available engine.

I have a 3GM30F in my boat and the exhaust hose is 2" ID.
