OK. Here's another one for all you clever lads. On a '77 115hp Johnson:
how does the tach signal get picked up at the engine end? Does the wiring
count firing pulses, or is there a magnet which gives a pulse each crank
rev?



If I could find the shop manual (which is definitely within 5' of me right
now...).

Sorry, no questions will be answered until this Senior Moment passes. Have
a nice day!
