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.

Wish it had solved my problematic engine. Now I have another spare part. Another post said his did not come with the nuts for the screw terminals. Mine did come with them?

by Johnna from Burleson, Texas on May 09, 2015
I will never use another boat supply company as long as iboats is around. I'm an online buyer and the website design is flawless please don't change anything unless it's adding even more details about the part your looking for

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.

A:
Yes this will work for your motor.

Q:
Have a 1981 50 hp Mercury SN: 5951883 will 18-5186 coil work?
A:
Yes it will work with your motor.


Q:
Can this replace3364409a?
A:
I don't cross reference that number. We only cross reference the following OEM numbers: 339-832757L4, 339-832757A4, 339-832757B4, 339-7370B13, 339-7370A13. If you need further assistance give us a call at 1-800-914-1123.


Q:
Does this replace 339-5288 ?
A:
No this does not cross reference with that OEM number. The number may have been replaced but we would need a serial number to verify.


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.


Q:
Will this work for a 15 hp Gamefisher Model # 225581503 ?
A:
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.
