TOPIC: 66 merc 500 voltage regulator

howdy to all, new to this forum, but i must say looks like its one of the best out there, espically when it comes to vintage boats and powertrains. anyways im startin to finish up the restoration on the old aerocraft and merc 500 longshaft, and just have to tidy up some loose ends, and one in particular thats bugging me is the voltage regulator and its non-functioning condition. on short trips etc... its not really a huge issue, but it would be really nice if i had a functional charging system, does anybody know where I may be able to find a replacement? searching various manf sites I can find plenty of listings for what appears to be a modern replacement for the 67 model year. does anybody have any experience with these? i would like to think they will work on the 66 but really dont feel like having a trial by fire. anyways any feedback would be greatly appreciated.

(It pertains mainly to the stack 6 motors, possibly one of the gang can confirm or clearify the application to your motor.)

it is a rectifyer not a regulater. if you run with the battery unhooked it will fry. any of the merc rectifyers work 2 yellow wires from the stater under the flywheel. 1 red battery wire

Thanks for the input guys looked over some older posts,and seems like a pretty simple fix.
