2006 Mercruiser 350 Mag MPI. Bravo 3. I removed the throttle body cover that had the serial number on it, and it blew out of the boat. I know it said it was manufactured in 2006, but, is there an alternative location for the engine serial number? I looked pretty hard, and could not see anything obvious. As you all know, I need the SN so I can order parts, such as a new cover....
