replacement coil question

Just bought a new coil kit for my outboard and I need to know if anyone knows how to properly connect the spring that connects to the plug to the wire.

The rubber boot, spark plug end.... With the wire cut to the length required, trim back 1/4" insulation again but do not solder tint the wires. Simply fan out the wires and fold them back against the insulation, cutting the excess off so that they do not exceed the diameter of the wire. Holding the spring wire terminal, estimate where the prong should be inserted so that the spring will be flush against the exposed wire. Hold the spring terminal away from the wires end (sideways) and insert the prong into the insulation and into the center wire, then swing the spring terminal in front of the exposed wire portion (makes a tight fit for continuity purposes).

Spraying the inner portion of the boot where the wire will insert with a small amount of WD40 makes the installation of the wire a easy project. That's it.... you're done.

Yup, that's a great post. I never could seem to get the spring clip just right, so its nice to know the correct technique.

That said, I don't even use the stock wires any more. Auto Zone sells very inexpensive wires with molded plug boots on both ends. You can get them in a variety of lengths, so it is usually possible to make two spark plug wires out of one, by cutting it in the middle. The insulation is the same diameter as the stock OMC/BRP items, so they fit the coils very well. I have a set on my 1972 Johnson 65hp, which now have about 100+ hours on them with no problems at all.
