I have a 1983 75HP Evinrude Model # E75TRLCTE. The #1 Cylinder is not firing. I checked the spark plug wire, good. Checked the ignition coil, good. My next step is to check the powerpack. I am following the OMC manual for the tests. My question is, if it is the powerpack does anyone know the powerpack part # of this model engine? I did a search here on the site and came up with an Evinrude/Johnson Power pack for around $80 and I want to make sure this is the correct one.
