Main Question or Discussion Point
Hi all, so my mercury 25 outboard starter was starting to give it up. I took it apart, and yup, the brushes were badly worn. Well, I have several generic brushes kicking around, so I simply swapped them out. Very simple operation. And yet after assembling the damn thing, it now runs backwards! The flywheel engagement gear doesn't jump up and engage the flywheel because it's run on a spiral grove machined in the motor shaft and the shaft has to rotate in the correct direction to make the gear spin upwards. I pulled the motor again and connecting it directly to the battery, and the gear doesn't jump up unless I put + on the case and negative to the power connection. How is this even possible? I didn't remove the gear assembly when I pulled the motor apart.
