The length and sizes worked well for me
Good quality, I would purchase again but I hope I don’t need to because my boat has zero room to work with in the engine bay

Great fit for Mercrusier 4.3l engine
Used on my 92 Cobia with a Mercrusier 4.3l engine. Direct swap and no issues. Came with good amount of dielectric grease in the plug heads, too.

Check your part numbers. Not for point style ignition.
Product came packaged well and looks like a good plug wire. I goofed my part numbers and got these for 3.8OMC with points ignition. These do not fit points style screw down cap as they are made specifically for electronic ignition. Just wanted to note for anyone working on their old boats. 1985 Seaswirl Spitfire with 3.8OMC

Fits perfect!
I replaced my original wires (from 1988) with these along with plugs, cap, rotor, coil and sensor and my engine runs much better now. These are the same length as the originals but thicker (more insulation) for less spark bleed. they fit great.

Defective boot split open but GREAT customer service!!!
So I was pretty happy with the product until the Boot on the #5 distributer split open after only a few months. I contacted Sierra via their website and, surprisingly to me after only a few hours, I had a response saying that they are going to send me a new set of cables!!! Not just the one wire but the whole set. Well done Sierra! I had originally gave the product one star but after dealing with them and the quick response, they deserve the 5 Stars now.

Decent product, solid price
Solid product for the spark plugs. I would give 5 stars however the ignition coil wire was so tight in the coil it was popping off
