Hi, Go to this site http://www.4shared.com/dir/8iGasxP0/sharing.html Look for Mercruiser Service Manual #24 and download This manual should cover 5.0L from 1998 upto mid 2001 It has all the procedures you need depending on type of motor, pickups etc. It is a BIG document (800+ pages), but you can electronically search Regards Share this post Link to post Share on other sites
