What to do if my Mercury Alpha has hard shifting into forward gear?
If your Mercury Engine experiences hard shifting or chucking/ratcheting when shifting into FORWARD gear, it could be due to the cables not having enough clearance to operate. Ensure the cables have sufficient space to move freely. Also, check if the control box is mounted too far back toward any fiberglass structure; if so, reposition it to prevent interference with the cables.
Why is power trim motor running, but the drive unit does not move on my Mercury Engine?
