1995 Mercury 90hp outboard used 1 of these for top cylinder. Bottom 2 I used 7". Working great. Old ones were shocking if touched. LOL

These actually had more resistance than the Belkin I wanted to replace. Not impressive. Worse was the fit into the top of the coil pack. Entirely too tight and too big to fit as it should fit. I used them for a bit and had to use a screwdriver to grab the edge of the terminal brass and force into the coil top. Not good. Yanked them off and trashed them. Embarrassingly expensive junk.90hp Mariner.
