Re: 1958 Evinrude Sportwin shift lever
Without a year/model specific parts book, I can't say for sure, but some models do indeed have a shift lever that will pull outward to release and turn down to make it easier to get the hood off. This is a special feature on the affected Evinrude models, different than Johnson because the Johnson doesn't need it. It is also standard equipment on Gale motors.
If it has both part numbers 11 and 16, it is the release type.
