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.

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

Does not work for Evinrude 140
by Joel from West Chester, Ohio on August 31, 2015
Do not buy these if you have an evinrude 140. The connectors pop-off the plugs and the coil assembly. One of the four I bought was broken also. I am trying to return them but so far this website has not been very helpful. Not impressed at all.

The wires were too short...
by Luis from Miami, Florida on July 09, 2011
My fault, then I discover that the OEM wires are made of metal so I used the terminals of the Sierra wires wich are of good quality and used them in mt OEM wires, problem solved.

Very high quality wires
by Joseph from Green Bay, Wisconsin on July 28, 2013
The silicone rubber construction of these wires should result in many years of dependable service.
