1967 Evinrude 18 fastwin shifter adjustment

Hey, I have done some searching but can't find what I need to know. I have rebuilt the foot with a new dog and shifter fork since the guy who rebuilt it the first time just use a brad nail rather than a cotter pin to hold the shift lever to the fork. So my question is i'm still having a problem with it wanting to pop out of gear. I know i need to adjust the Shift lever but which way do I need to go. Where the shift lever attaches to the shift cam it has a 1/4 circle plate with two grooves cut in it and I have mine in the bottom one. Any guidance would be great.

Take a look at my thread maybe it will help...

Thanks I read your post but apparently when you aggravated over you boat motor not running right you should cool off before you do research or you miss things. What I needed to know was in there thanks

Haha ya it never helps to get aggravated.
