When you change motors, you need to get the controls and wiring harness with it. Tach will have to be changed as the force has a non-adjustable 12 pole tach. I know where a good 115 Johnson is. It does`nt have t&t.

those motors have very small wires for the powerpacks and trigger assemblies, with little connectors that break inside but you cant see it. Do this.. cut the wire at the connector to the pack that isnt firing, and put a new spade on the end of all of the wires coming from the pack to the terminal block, Do the same with the little trigger wires. I bet it will fire then. If u have any questions Pm Me. I had one drive me nuts with intermitent firing, and thats all it was, broken wires in that little section right above the spade connectors.
COMING SOON! .. THE STICKLE HOOK " the stay level sickle hook". sits level in the water with all knots.! Provides better hook sets and more natural jigging motion. No more adjusting the knot, gluing , or tying loop knots that cause the hook point to tangle in the loop, or worse knick the line.. The jighook that will make all others obsolete !

generally there are 2 power packs, one pack fires 2 plugs, and the other pack fires the last plug, but either pack is capable of firing 2 plugs.

Leaning Post is right on the two double packs firing only three cylinders. With a little research you can swap the packs around and omit the one leg that is not firing. been there done that.
