    750zxi runs, no power, no throttle

    1997 750zxi. Ran fine last year, put up for winter and have problems now. It will start and idle fine. seems to have some throttle when just running on the trailer. When put in the water, max speed is about 15mph then starts slowing down to where it will barely go any faster than idle. Have changed out inline fuel filter and put in carb kits in both carbs. Fuel lines have been changed out to deal with ethanol issues. Now what?? I dont think it is anything to do with temp sensor shutdown since it does start out with power above what I have experienced when it does overheat. Seems to me something with the fuel flow. Any ideas out there?

    What do the spark plugs look like? Probably fouled.
