[jspana]

To the Gurus out there, I have been having some trouble with my outboard, Running rough and wont rev past 3500rpm.. I took it to a shop and had them scan it.. It came back with 3 codes, EST2 EST4 EST5 all open.. Any help would be sooooooooo much appreciated.. thanx

That means cylinder 2,4,5 are not firing ,check the connections at CDM module and ECM, CDM grounds and coil wire for damage.
