Installed shift rod to specs in 79 manual for model 150949-1979 v6 150 evinrude motor. No reverse! Checked two manuals and seloc manual was different than an original 79 manual by .64 inch (11.7mm or 1.168cm). Is seloc manual right? I tested shift before putting LU back on and had R N F. I can correct without take LU off again so hoping 79 manual had misprint.
