SierraInternational 18-8819-1 Premium MagForce 7" Marine Spark Plug Wire Lead for Mercury/Mariner and Chrysler Force Engines (18-1202-9)

Seems to be pretty good quality stuff. Only complaint I have is on my mercury 25 horse it required a 5 inch and a 7 inch spark plug wires. Good thing I ordered 2 inches bigger than I needed, as these measure from tip to tip. Had I ordered the 5 inch and 7 inch wires they would not have been long enough.

I love this plug wire. I absolutely hate the price. $25. Come on.

Had a bad wire and got these to fix for my ancient 1975 Mercury 110 9.8hp. A little longer than I needed but works great and I have spark on both cylinders now. Cant complain!

I ordered 3 of these for a 1989 80 hp mercury 3 cyl. along with coils, the center and lower 1 fit but the top was to short. Had to send back and order a 9". NOTE they are 7-1/4" from center of plug boot to end of coil connector. They seem to be good quality, will update when I receive the 3rd and get it running

Original wires starting to show age. Replaced with these and can tell a little smoother idle, top speed, and seemingly better fuel consumption.

I replaced these when I rewired an old 9.8 outboard. It runs great now, starts right up and runs amazing for something older than I am.

Fit bottom 2 cylinders on 1995 Mercury 90HP outboard. Top needs a 9". All worked great.

Fit & work well

Bon

Worked great and arrived early
