[scott6363]

My 4 stroke outboard runs fine when at speed but when I slow down it idles rough at about 900 rpms then it will idle up to 2200rpms and stay. Has anyone else seen thiss problem?

Need to have it checked with diagnostic program to see whats causing it, should still be under warranty.

I know that some motors have to change the entire engine harness(covered from warranty) and/or idle speed motor. Contact your dealer to get a correct diagnosis.
