Currently I own a 20' Hydrostream with a Mariner outboard, but I'm looking to buy an express cruiser in the next year or two. Since I've heard the horror stories of buying a used boat, I'm starting to educate myself now. What is better in terms of perfomance, maintenance and gph, a stern drive or an inboard? Gas vs diesel? I plan on 75 hours per year on the water. I've been looking at older Chris Crafts and Trojans with inboards, and newer boats like the Bayliner Ciera with stern drives. I'm a shadetree mechanic, so I will be doing my own maintenance (within reason), but I'm not up for doing an engine rebuild every 3 years. What parts are most likely to fail? Since I will be purchasing a used boat and, I plan on having a compete marine survey before purchase. My budget is $7,500 to 10,000.<br />Thanks!
