How many amps would you think the alternator pumps out on a 1987 30hp 2 stroke?

Its a Mariner. Just curious Because I use one deep cycle battery and a 46lb electric troller and I want to have an idea what kind of charging power this engine provides. Worst case scenario I can pull start it easily but I will have to make sure the battery is fully charged at the end of each trip of course.

I would guess 6 to 10

one hour of running the motor at full speed will give you about 7 mins of trolling

7 Amps from the stator, less any boat electrics running. It's very little current since one 50W light draws away 4+ Amps.

sounds like just basically enough to recharge it from starting it up. Would have been nice though if they could have something stronger but hey I won't complain. I think some of them older outboards didn't even have any charging ability

My mariner came with a tiller handle and no electric start. The output from the stator was "unused". I soon changed that, and adapted every light in the boat to LED. Whole boat draws less than 2 Amps, leaving me plenty to trickle charge.
