I have an old 9.5 Johnson outboard, not sure which year but think 60s or 70s (any good way to find out?). Went to use it today, backed out just fine, but when I switched to forward I got nothing. I popped the top off and looked at the cable up at the top near the shifting switch, it appeard to be lifting when I shifted into forward, but still nothing. I don't really know anything about fixing outboards. If I knew which year it was I could buy a manual off here. Any suggestions or ideas? Thanks for any help!
