[C320-list] FW: Repowering- engine choices

[Robert Seastream]

Our 2002 has the Yanmar 3GM30F.  A bit louder than most, but  
reliable.  My fathers Universal on his Cape Dory 28 was as loud.  I  
have noticed that Perkins diesels are quieter.  My understanding on  
diesels is that they can give several thousands of hours of service,  
so I wonder why (I didn't see how many hours on your engine, or if  
there were other reasons) you'd repower rather than rebuild.
