    I have a 1979 175 hp merc black cat motor i cant get it to pick up and plane off. It runs good till about 3/4 way through the throttle then it bogs down and wont go any faster and starts missing. I have replaced the plugs and a switchbox that i wasnt gettin any power off of the fuel jets seem to be clean and working properly. THe fuel line is in good condition and im at about at wits end any help you can give would be greately appreciated.:confused2:

    Sounds like its not getting the right amount of fuel supply. I would start with the basics of spark test and compression test and check every inch of the fuel system
