Mercury 1150 Outboard Ignition Coils (set Of 6) on 2040-parts.com

Used ignition coils from a working Mercury 1150 serial # 59398XX

 

On the second photo, I've enhanced the stamped part #'s by typing them in pink

I've tested these off the motor with the following results.

(Rows are referenced From second Photo)

Top row:

#1 - Primary coil  .1 (my ohm meter can't go lower)  Secondary Coil 921ohm

#2 - Primary coil  .1 (my ohm meter can't go lower)  Secondary Coil 939ohm

#3 - Primary coil  .1 (my ohm meter can't go lower)  Secondary Coil 965ohm

 

Bottom Row

#1 - Primary coil  .1 (my ohm meter can't go lower)  Secondary Coil 964ohm

#2 - Primary coil  .1 (my ohm meter can't go lower)  Secondary Coil 983ohm

#3 - Primary coil  .1 (my ohm meter can't go lower)  Secondary Coil 960ohm

 

The service manual has the primary btw .02 - .04 ohms (my meter doesn't go that low so it shows .1)

The secondary should be between 800-1100 ohms.

The issue I had with the motor was that it would run well when cold, and it would continue at power. But once I dropped into idle & tried to go back to power, it would bog down and not want to run past 2000RPM If you're chuckling because you know what my issue was,that is no problem. I was able to convince my wife to let me by a new 4-stroke!

Sold as seen.
