Careful, that "lighting coil" may not be rectified. Good enough for
lights, but not for charging.

I'm sure it isn't, that's why I mentioned adding a rectifier/regulator. I
was thinking of maybe one of the generic ATV/off road types like this:

Missed that part, but there's not much charging going to happen. Even
the 10 HP outboards rarely put out enough to make much difference, and I
believe you said 4 HP.

Frankly, our 55 amp "automotive" alternator won't fully charge the bank;
maybe 20-25 AH in the first hour into a 120 AH battery.

That's why I am happier with solar. After it charges for 3-4 days, the
battery's at full charge, then it supplies enough that we rarely need to
use the engine except for moving for 3-5 days.
