Can anyone give me some guidance with the proper start up procedure for a new engine. a; I'm looking for specific info for priming the oiling system. b; Will I need to contact a tech with a laptop and Mercs program to reset the ECM to the break in mode? c; Or can I add 2 stroke oil to my fuel during the break in time period? Any accurate information will be extremeley appreciated.

Key in the run position but with engine not running... 5 times from idle to WOT... gradual acceleration and then back. Is there a certain amount of time this should be completed in? Thanks for your guidance, Is there any particular prayer that should be said prior to starting this procedure for a long healthy life of my engine?
