I have come across an early 90's EBBTIDE Campione 204. It has a 350/V8 with a Yamaha I/O drive. I havent put the boat in the water yet but how difficult would it be to convert it to a mercruiser setup? Bolt pattern, transom hole cutout, etc... To the best of knowlede the drive system works well. The boat needs a little TLC but the kicker is they will sell me the boat with trailer for $1000 OBO. They are not wrenchhead's like myself. Any help is greatly appreciated.
