A Bass Best Friend
by Henry from Fountain INN, South Carolina on November 19, 2015
I am shock that I actually order a part for my boat and it was exactly as it appear in the catalog, and it it fix exactly in place for the parts it was replacing. So I have order 2- more and I will have tune up my boat for a 1/3 of the cost for the parts quoted to me. I will indeed pass Iboat to all of my Bass fishing buddy. ....Go iboats

Replacing coils as preventative maintenance
by Tim from Winston Salem, North Carolina on June 15, 2016
Good product, I bought and replaced all 6 for my 30 yr old Mercury XR2 Blackmax, as preventative maintenance. NO instructions included so I don't know what the extra cylinder included was for. I also purchased the ignition wire set 18-5225 and made my own plug wires. My engine runs great as it did before. I did keep the old original coils just in case. Fast service and convenient shopping for me.

Disappointed
by David from Dighton, Kansas on June 07, 2013
I got the new coil and the threads were different than the original coil. I live in a small town and there was no place open to get new nuts so I tried using the old ones anyway, broke one of the terminals off. My fault, shouldn't have tried it. It would be nice to send new nuts if the threads are different.

Perfect replacement coil pack.
by Robert from Kaneohe, Hawaii on August 04, 2016
This part is an exact match of the OEM part. It is easy to remove and install yourself. The price is very reasonable. The are very few businesses on Oahu that carry this part and it is way more expensive. Ordering was easy and the shipping was fast. It is best to change your coil packs before they give trouble. You can keep the ones you remove as spare. Change your wires when changing your coils to have peace of mind and a pleasant day out on the water. A little insurance goes a long way so that you are not stranded out on the water.

by Butch from Winnemucca, Nevada on September 30, 2014
I have had this 15 hp Johnson since new, 1985. This year it started running rough erratic no high speed poor trolling. After walking through step by step troubleshooting, I was only running one cylinder, one bad coil. I replaced both, perfect fit, half hour job. First pull my old motor was new again. Better than any computer Plug and Play!!

Awesome coils
by Gary from Westerly, Rhode Island on September 12, 2014
My boat was running a little ruff. It is a 1993 Johnson 200 Venom series. The previous owner had replaced half the coils,and I have been replacing plugs every season. The plug wires were original. I bought all new coils, wires, and plugs changed everything out in an hour and 10 mins using die electric grease and now it starts and runs like new. Best $250 I ever spent.

HOT! HOT!) - Thanks, Mike

This is a single coil.


Q:
I want to use these in an Old fifties Seabee will they work they look like the right part my question is output of spark Voltage?

Q:
What is the ohms reading on a new coil mine has 240ohms and the old one i'm replacing is 840ohms and the shop manual states the reading should be 800-1000ohms so is my new one bad?
A:
Yes if it's reading outside that then you might have a defective coil.

This will not work. You need 116-2379K2.


Q:
Is this interchangable with coil 332-4895? inline 6 150hp 1973 model?
A:
No this does not cross reference. You need OEM number 332-4895T2 for your motor.


Q:
What is that little cylinder that comes with the coil?
A:
Sierra said that depending on the application you might need to use it. You would take off the housing of the ignition coil and put it in there with a screw though it. They didn't have a name for it though.
