Boot does not fit properly
by Donald from Ochlocknee, Georgia on August 28, 2017
The side that is opposite to the spark plug does not properly fit on the connector there ( the boot is too big) on my 1990 Evinrude 150 (which this was supposed to fit). I'm going to try and put some hose clamps on to secure it but they may cause early failure due to the extra wear. Would have preferred if they fit correctly (I've seen others complain of this same problem, but hoped it wouldn't be applicable to me).

plug wires
by Dirk from Willmar, Minnesota on June 23, 2016
I ordered the wrong ones at first (to short), but iboats was very easy to work with on the return of the wrong parts and once I got the correct ones I was very happy with them, they seem very well made.

Awesome Wire
by Gary from Westerly, Rhode Island on September 12, 2014
These look like a quality product. Also physically they really dress the motor up. Nice silicone boots to get a good seal.

Weekender
by Michael from Mukwonago, Wisconsin on July 29, 2014
Ordered the wires for a 1991 Johnson and recieved them very quickly. I'm very pleased with the speed of shipment and the wires are working great. The old wires were 7mm and the new ones are 8mm, so it's an added bonus.

Perfect fit!
by Paul from Quitman, Georgia on February 28, 2014
Exactly what my poor old Johnson 40 needed. I finally got that little "miss" at idle that I've had since I bought it 2 years ago. Thanks iboats! RUSTY

Q:
Are these OK for a Johnson 100tlr79?
A:
According to Sierra all Johnson spark plug wires are the same you just need to know the length you require. So if 9 inch will work then yes these can work for you.


Q:
Hey folks, have a 1985 Johnson 150 GT model J150STLCOH, will these wires work as replacement?
A:
Yes this will work as a replacement, but you will need to verify if the 9" length is suitable for your motor.


Q:
Will these work on a 1986 Johnson 110 v4?
A:
It will work on your engine. You will just need to confirm if you need the 9" length as Sierra offers various lengths.


Q:
Hi, will this wire work on an evinrude XP200 1988 V6 G1742488?
A:
As long as 9 inches is the length you need then yes this will work for your engine.
