I currently have a 2007 115hp optimax and I am looking at he mercury website at the engine specs. It looks like the actual "engine" is the same for the 75-125hp models as far as displacement goes. Since this is computer controled fuel injection, I am wondering if it is possible to have someone tune the engine to the 125hp mark rather than the 115hp or if there are physical differences like throttle body, injectors, exhaust plate, or something like that.
