I have a 1995 Grady White 208 20.5' Cuddy Cabin, which is currently powered by a 1995 175 Yamaha. Looking at re-powering with a 200 Yamaha 4-stroke. I currently get about 2MPG with the 175. What range could I expect with the 200? I'm concerned about the extra weight of the 200 and its effects on trim. Any first hand experinces with the 200 would be appreciated.
