Hello my name is ***** ***** am I speaking with?
When it goes to full throttle, does it just sort of kick in, just like that?
Are you able to check for spark to see if spark is dropping on a bank when running the motor?
The easiest way to do it is to get a timing light. Pull the engine cover off, run the engine until you can duplicate the problem. Then hook up a timing light to each plug wire one at a time and see if the timing light flashes or not. If it does, there is spark, if it does not, there is no spark. Let me know what happens.
You want to put the boat in the water, running the engine over idle when on the garden hose is bad for the engine.
That being said you can definitely check it at idle when on the garden hose, but if it does show spark on all 6, you would want to double check it by running it in the water next.
Got it Terry,
next step is to disconnect the charge coil from the CDI box. Get a volt meter and set it to AC, and measure the voltage on the red and brown wires, and then on the black/red and blue wires and let me know what you get. To measure voltage, have a helper crank the engine over while you are checking voltages at the plug. Is this something you can do?
