"I am having a problem with my Alpha 1 outdrive. I can feel/hear the lower unit grind when I only put it into the forward position. The slower and easier I push, the worse it is."

"The Throttle. When I put it in gear I hear it grind. The slower I move the throttle into gear, the worse it grinds; however, It will go into gear everytime."

"My Alpha 1 does the same thing, Sounds normal to me. Typical for Mercruiser.
Has it got worse over time or allways been that way?"
