Congrats on the purchase! I took my Cary in on a trade and have had so much fun with it I hate to sell it. I have had it for 4 years now. It has quad Mercruiser diesels (same as the powerstroke ford engine) installed in 2001. I have had no engine problems. The gas motors are cool, but temporary. Compared to what most of us are used to, your never going to make these boats go fast. I would recommend the diesel route. There are plenty of other systems to maintain if you like to tinker.
