That's normal. The battery is supposed to be the voltage regulator. Mine was that way and I didn't like it. So I got a rectifier/regulator from a newer merc and put that in instead. I was worried about my electronics at 16v, Spent a lot of money on them, radar, downrigger temp and speed. Hummer 998, etc. Piece of mind. Yours is working properly though.

I was not able to find one that mounted in the same location. I had to extend wires and jury rig the mounting location. Make sure it has a good heat sink where you mount it.
