If your motor doesn’t operate correctly, double check that the wires go to the correct switch terminals. Also, make sure the wiring isn’t loose or broken. Use a magnifying glass to make sure not even a tiny strand of wire is accidentally touching another wire or terminal. here
Solder the black (power negative) wires to the DPDT switch.
4. Connect the yellow and blue wires to the motor terminals.
AC motor wiring diagrams are available for all of our induction motors, but we will explain how to reverse t he motor throughout the rest of this post. [links]
For this example, we will use an AC motor that has two copper windings within the stator—a main winding and a starter/auxiliary winding. Each winding is comprised of a bundle of copper wires that carry electric currents and produce magnetic fields. The starter winding is typically composed of a smaller wire, resulting in a bundle with less magnetic strength than the main winding. The resulting electromagnetic activity is what is responsible for energy generation and for keeping the rotor in motion. more
The main and auxiliary windings sit perpendicular to each other, creating both a vertical and horizontal field. Each winding fights to have its own charge acknowledged—when the rotor aligns with the one magnetic field, it is then pulled an additional 90° in attempt to align with the second one. more
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation. [links]
Motor rotation is essentially created by the manipulation of wires and magnetic fields. Thus, you can often reverse AC motors by switching the wire connections. This is as easy as unhooking and re-crimping the designated wires. (Note, not all AC motors have the ability to be reversed, but all of Groschopp’s AC motors can be).
OK, so I finally got the throttle cable disconnected. Pushing that out of my way, I also disconnected the shift cable. And attempted to shift it by hand. The prop spun correctly in forward (like I knew it would), and it spun both ways in neutral. However, after sliding it all the way in reverse ( keep in mind it would nt even come close to sliding back that far by just using the throttle control) the prop wouldn't spin either way. Meaning it just seemed to be locked. So even if I adjust this so that my throttle control goes back all the way, it's still not going to resolve my reverse issue.
Re: no reverse - adjusting shift cable more
In reading through all of the relevant posts, it sounds like I have to adjust the shift cable. However, I don't really understand the directions as I am not just a newbie to boats, but am also a newbie to anything mechanical. Meaning, I have no idea how to interpret the directions I have been reading.
Re: no reverse - adjusting shift cable more
I have a 1974 Sterncraft (tri hull). It is an 1150 mercury outboard motor, inline 6 cyl, 115 HP.
1. If I shift it into fully into forward the throttle control is at a 90 degree angle from neutral. If I pull the control back to reverse it only goes back abou 25 degrees and does not engage in gear.
2. While the control is pulled back in reverse, the prop spins both ways (as if it's still in neutral.
Fig. 7: Once you take off the top, be sure that the rotor (surrounded by blue) does not fall out because it's a pain to put the commutator back into the piece that contains the brushes. It's up to you if you want to completely remove it though.

Rather than a gas engine, you might consider an electric motor for your karting project.
Fig. 1: Remove the two circled bolts in that retain the solenoid in place. You will not be using the solenoid so do as you will with it. more
What follows is a simple DIY project which will turn an ordinary autmobile engine starter into an electric motor with forward and reverse!
Most auto starters work on the same basic design, so the brand shouldn't matter too much. The starter in this plan is from an older Nissan Sentra.
