    I'm reallly frustrated and feel like I was ripped off

    I had a perfectly good running 89 Nissan 90HP but wanted to get a bigger motor because I felt with all the weight I have on my boat I was underpowered. I decided to sell mine and bought a 2001 Nissan 140HP because I knew that it was the same motor as the 115Hp and if needed I could detune it...

    Im repowering from an 1988 Nissan 90 hp to a 2001 Nissan 140 hp. I have a 21 gallon tank. Should I expect to use more or less gas. I'm thinking since motor is newer and will have more power I will use less, but any advice or thoughts? I was currently underpowered.
