A catamaran on outboards can equal the mpg of a trawler on diesels, so if you want to convert a big heavy boat to ob's you better have lots of cash for fuel.

Of course you could make an argument for some very cheap V8 gas engines on shafts. I'm no expert on these engines but you can buy them brand new for a few thousand $ and maybe swop over the marinising gear off an old scrapped one.
