i have forward no reverse, and then it clinks until it clunks into forward. at a speed to fast to safely go onto a trailer i have no "no wake" speed. then today i tried adjusting it, and then i got reverse but then no forward, or should i be doing this on water? every marina, said the boats to old to touch so im kinda screwed here? one guy said it was the shift cam, even though i told him i didnt know crap about adjusting thse cables. ive read a few diagrams, but they say stuff about barrles on the lines. i only have 1 barrel and it doesnt spin, and thats on the line going to the outboard...i can manualy shift it nto reverse and forward with my hands, if the shift cable is disconeccted????
