Yes, 38 is running great (96 mph)... but have be careful with the drives.. change oil every third outing and inspect the gears twice per season.

Wow, that's smoking Did you change to shorties or are you running the same drive height as when you got it?

on the gas milage, i drive a 47 with twin 1075's it averages .82 miles to the gallon according to the smart craft gage at 85 mph. the boat ran 122mph at the factory and is a standard 47 set-up it also has a 400 gallon fuel capacity
