Re: diagrams for evinrude starflite 90s
The Starflite 90-S was made 1964 and 1965. The electrical wiring was different as night and day betwen the two. 1964 had a junction box mounted in the boat. 1965 has diodes mounted on the side of the flywheel guard, and a finned voltage regulator on the rear of the powerhead, no junction box.
Look for a quarter-sized disc on the powerhead, near the rectangular plate on the top, with the model and serial number stamped on it.
EDIT: IF you have a 1964 and you don't have the junction box, you have a problem. That stuff is worth as much as the whole rest of the motor. Likewise, the push-button remote control....got that??? The control was used both years.
