Hi,
I am new to this board. I just bought an older 3.5 HP Mercury [serial No.6626591] made in Mexico[1983 ???]
The problem with the engine is no spark. I measure ignition coil [part No.87885] ,and reading was:
-primary wiring 0.9 ohms
-sec.wiring 2.84 K/ohms
The ignition/spark wire is turning in...
