I am looking to buy a Ranger Cayman 191 with a 04 200HO DI, and was told by the dealer that it would get better fuel mileage with the 200 rather than a 150 around 4000-5000rpm. Is this true the hull weighs 1,180lbs. I have a Sratos 285 Pro XL with a 175 Fast Strike Johnson, and it has been great, but it like's fuel. I just want to buy the right one, any help would be appreciated.

Thanks
