Review for Ignition Coil for Johnson/Evinrude 582995 584477, Mercury/Mariner 802371A1, GLM by a CustomerJanuary 15, 2009
Perfect match to 40yr old OEM parts. Delivery was on-time around 3:30 PM, had the distributor system torn down and put back together in less than an hour (I'm a forester, not a mechanic)pulled the cord and found out just how HOT these coils are (note: never pull the cord while touching the plug wires HOT

Follow up on 5 out of 6 isn't bad by Anthony - Key Largo, FloridaSeptember 20, 2011

5 Out of 6 Isn't Bad! by Anthony - Key Largo, FloridaAugust 26, 2011
Ordered and received 6 of these coils for my 1993 Mercury 150HP outboard to replace all the original coils as preventative maintenance. Installation was fairly straight forward with no problems. I started the engine up and noticed it was running rough/missing...one of the coils was not producing spark. I replaced that Mallory coil with one of the original Mercury coils and it ran fine. Frankly I'm surprised, having relied on Mallory ignition products since the 70's. I was pleased to see that these coils are manufactured in Germany, but am a bit disappointed in their quality control. It's been a month since I returned the defective coil to iboat...still waiting for a refund. According to iboat, it must be shipped back to the manufacturer for testing, prior to credit being issued.

Works great, but.... by Gary - Shelley, IdahoJune 28, 2013
I installed these to replace the OEM coils that were arcing out on the bottom side. Mounted these in the exact same spot and then tried to start motor....it wouldn't turn over. had to take motor apart again and noticed that these are bigger than the OEM ones by a couple of mm and that the flywheel was catching on one side and ended up busting out the screw threads to the mount plate. Now I have more parts to replace, if I can find them. If you buy these don't put them at the exact place the old ones were and be careful when adjusting. Your flywheel will catch on the outside and rub bad on the inside.
