Could I get engine serial number please?

Do you have a peak reading volt meter, spark gap tester?

checked the blue wire while motor was cranking I had 82when I stop cranking it peak to 139 using a DVA
Customer reply replied 11 months ago
I check spark on each cylinder and only had spark on number 2 cylinder I got number 1 to spark initial crank for like half a second
Marine Mechanic: Tan, MerCruiser Certified Technician replied 11 months ago

The spec on the blue wire at cranking speed peak volts 180-400 volts. So your stator is weak.

Replace the stator. The only reason it sparked is the voltage spiked. Still the voltage is to low at cranking speed.
