1. Check motor horsepower and frame size (see pictures left).
2. Check motor manufacturer.
3. See Wire Size Chart (below, on the left) to ensure proper wire size.
4. See wiring diagrams (below, on the left) to connect AO Smith motors to factory Aqua Marine wire harnesses to ensure proper wiring.
5. Ensure that the capacitor (the large box on top of the motor) is in the same position as the motor that you are replacing to prevent problems with mounting.
6. Make sure that the motor that you purchase can be used with the voltage at your lift (115V/230V).

See our Motor Troubleshooting Guide to determine if your motor needs replacing or if you have some other problem with your switch, wires or power setup.
