Question edited for clarity.
Question moved to Boating category.
The new Alternator or the Rectifier is faulty or incorrectly wired. When revved up it should be generating about 13.2, to 13.8 volts and supplying to the battery. The 12 volts at idle is probably your battery voltage.

The videos below should help. Although the first one is an inboard, the theory is the same. On an outboard, you can disconnect the linkages, verify that the engine is in neutral, then adjust the linkages to fit. Then adjust the slack with the same amount of turns on the adjusters. Lock the settings and that's it.

Here are the parts schematics, but you need the proper engine model number. The best way is to go to a local Johnson outboard dealer as they will has all the diagrams
