I just bought a boat that has a Mercruiser Alpha One Gen 1 outdrive. It will shift into reverse and into neutral just fine. It won't shift into forward though. I pulled the lower shift cable off of the lever and tried manually pushing and pulling on the shift cable end and get the same results. I pulled the outdrive off and can shift it into forward and reverse with no problem. I triple checked alignment with the two shift rods. Everything looks fine. I've owned a boat since I was 5 but this is my first inboard/outboard set up. I've read several of these posts to try to educate myself but I'm still having the same issue. I'd appreciate any help that anyone can offer.
