Anyone know how to get the plug wires out of the coils on a 77 Johnson 115? Also the part number for new wires
I can't find these answers anywhere. Thanks

Re: plug wire removal?

Are you sure the wires actually are removable types? Some coils have the spark plug wires molded into the coil assembly and can't be removed...well without damaging them anyway...

Some plug wires screw onto a pin in the coil. That pin looks like a wood screw pointing at you.

There is a pointed threaded prong within the coil that the plug wire screws into. Simply unscrew it, then screw the new one in. The following may be of interest to you.

(Replacing Regular Spark Plug Wires)
(J. Reeves)

If you also need the spark plug boots and the spring terminals that connect to the spark plugs, purchase them from your local dealership (OMC Part #581027). This includes one boot and one spring connector. Price is about $3.25ea.

Purchase whatever amount of spark plug wire you need. Be sure to purchase the kind that has a steel twisted wire leading through the center of it....... not the carbon type plug wire that many automobiles now use.

Using your old plug wire, cut the new wire to a length about 3/4" to 1" longer. If you have no old plug wire, just make sure that the wire is longer than you'll need as you can trim the other end later.

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 as explained above. 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.

Are y'all sure the 77 has the screw in type? On another forum they said the 77 115 Johnson the coil and plug wire are 1 piece. So to.change the wire I would have to change the coil.
