I concur complete with Bob Austin about Mercury I/O's not being the best choice for your project. My experience with I/O's is that they all require more maintenance than direct drives or outboards. If you are committed to an I/O due to design factors I think most of your prospective buyers would feel more comfortable with your engine choice if you were running Volvo diesels.

It is with great pleasure to write that after two years of intense study into the market of power catamarans I am building two powercats at the moment. The one will be a 36 ft sports cruiser and the other a 48 ft leisure cruiser with two double cabins. I am sending you a rendering of the 36 ft and will later send one of the 48ft. After a great research world wide I came up with and European style for the 48 ft and would like to share this with your readers and would like some feedback on these models. The 36 ft will be powered by two 315 horse power yanmars with bravo mercruiser stern drives. The 48ft will be powered by two 380 hp. Both boats are being build out of composite material to decrease the weight Launching dates will be mid October and end December. I will forward photos at later stages of the building process Thanks Mark Nicholson [demime 1.01d removed an attachment of type image/jpeg which had a name of FWD_Perspective.jpg] [demime 1.01d removed an attachment of type image/jpeg which had a name of AFT_Perspective.jpg] ------------------------------ _______________________________________________ Power-Catamaran Mailing List End of Power-Catamaran Digest, Vol 29, Issue 1 ********************************************** __________ NOD32 2368 (20070701) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com

The I/O's would be a huge mistake. Inboard diesels are the only way to go on the 48. Outboards - maybe on the 36. I repeat, the I/O's are no way to go. Scott Clark
