    I dont think youll notice a diffrence but will depend on the hp rating of the motors. For example I have a doral 230cc with a HO 350/300hp and a friend with the same boat but with a LX 454/310hp and mine faster top speed and both about the same on gas. The bigger motor might use more fuel but it wont be working as hard as the 454 so i dont think there will be a big diffrence in fuel cost. What kind of boat do you have?

    I believe stock 502's are rated at 415HP.
