I have a Tohatsu 6hp with the charger-alternator, installed by shop I trust. They tested output at 3 to 6 amp at 1/4 to full throttle.
This is just a trickle charger, enough from about 1hr run time at 1/4 to 1/2 throttle for the depth sounder all day. Try to run more than that, like nav lights, on just an hours charge a day over a few days and the lights will dim.
If I have the nav lights on, it may only be for an hour or so at dusk as I return to the marina, and I may have the motor on for the last half hour, the lights get brighter when the motor is on.
It would take a lot of run time to over charge the battery.
