"They have a number of different names - charge coil, charge stator, lighting coil (depends who you talk to).
On your model it was called a "lighting coil assembly" and it has been long discontinued.
You could possibly find used parts from a similar vintage electric start model but I personally would not bother.
These models put out limited "charge" power, such that they could keep a "fully charged" battery "topped up" if it had a minimal draw (nav lights and maybe a fishfinder).
Additionally, all rectified power sources (common on outboards) work on a linear scale, so if it has a 6 amp system it only puts out 6 amps at full throttle - at idle it's barely putting out an amp.
So if you add a trolling motor in particular you would have to run at wide open throttle for about 12 hours solid to recharge a group 24 battery (and that is common on many outboards, regardless of mfg upto/including 75-90 horse models until very recently) - they just didn't do much more than "trickle charge" the battery.
If you still want to go that way you would need a lighting coil and a rectifier (retailed for about 200 bucks when they were available).
One last question for ya, is the oil pump/system still intact on your motor?
Yours should have the gear driven oil pump - and it is a good system if it's working. Just make sure it is before you try running straight gas..."
