    ideas on new ECM for 2004 GTX 4tec

    It would appear that I need a new ECM for my 2004 Sea Doo 4tec. Number on the old one is 664564. I do not recognize another part number on it. Issue with it is that it is not turning off the power on the electronic items when the DESS key is removed... thus, over a few days, the battery dies.

    Can someone fix this and/or do I need to find a replaced? If replacement... any ideas... or anybody got one they will let go of cheap?

    Add a 420 to the front of that number and you'll have the part number. Search on ebay or ask in the classified to find a good used one.
