I have this 1991 Yamaha 4MLHP four horse outboard, and browsing through
Yamaha's parts catalogs, I see that there's an optional lighting coil
available for pre 88 models and post 93 models of the same motor. Don't know
why it skips the ones in between. Looking down through the holes in the
rotor, it appears that mine has the mounting pads for the coil. Anybody know
any reason why I couldn't buy a 94 coil, stick it in my 91, add a
rectifier/regulator, and run some nav lights off it, maybe slow charge a
battery? How much current should I expect to get out of it? Couple of amps?
