thanks again and yes, the limp mode description is different from my problem the more I read the more learn these forums are a great. I'm going to start repairs soon and I will post my results. My wife's family has been a Nautique family starting with a 1965 glass ski nautique

That's not a description of Limp Mode AKA Power Reduction Mode for your 06 Chevy engine, but I think you've figured that out already.  Here's a link to a manual that may or may not help you, but it describes power reduction mode on page 15 of the printed manual. I think you're probably on the right track with the Throttle Position Sensor

I did search planet nautique and found other problems similar to mine, mine would only idle in gear no matter how much gas you gave it. I also read that it could be a throttle position switch.

There are only two events that can put the PCM Excal 330 into limp mode. One being low oil pressure the other being high engine temperature. Assuming you have confirmed you have normal oil pressure and engine temperature the issue you are experiencing is due to a faulty oil pressure SWITCH (not the SENSOR) or a faulty engine temperature SWITCH (not the SENSOR). There is a lot of information on PlanetNautique.com about limp mode in newer engines including some pictures of the location of the switches.
