I hoping that you can part some of your infinite wisdom on me. I am looking at 02 Nautique that has the 5.0 motor in. In talking with the owner he told me that it was not EFI, but Throttle Body Fuel Injected. I am not sure what the difference is and was hoping that someone could explain this to me. Would there be much difference in maintenance vs if it was EFI, what are the biggest differences between those two set ups? Do you think that there would be an issue using this set up on a short lake and skiing 36 mph? Any other information that you think I might need and I am not asking, please pass it along. I really appreciate everyones help in advance.
