I am doing this sunday 5-10-09 so if anyone can help please call me asap 269-998-5914 thanks! Jeff.

If your Merc ignition is good , you may want to reconsider that MSD system. They are discussed at great lenghts here as to the reliability issues they sometimes have. I have a OEM thunderbolt on my 525sc and it works perfect.
