Description:
|
This is a black box which interfaces an old OMC (Gale/Johnson/Evinrude) 2 cylinder outboard with an automotive tachometer. While this interface has only been tested with the OMC universal magneto, I expect it would work on most any magneto that can produce two pulses per revolution with a little tweaking.
