I am looking at purchasing a 1996 Carver 355 aft cabin with twin gas Crusader 454 XL engines rated at 350 HP each. The engines are very clean with only 470 hours and are NOT fuel injected. I have searched all over the internet for realistic cruising speeds, gph, and mpg rates and the numbers are all over the place. I would like to get some real world information from someone who actually owns and uses this same boat and setup. My wife and I really like the layout and space for the size of the boat. We will mainly cruise in the PNW (San Juan Islands) where everywhere is within 40 miles or less. Also, any known or common issues with this model to look for would also be helpful. I already know the aft aux fuel tank inside the swim platform are known to leak. (This one does as well)
