you will be fine with the 1/2hp. The Hayward will move quite a bit of water as well. It may not move as much water as the 3/4hp but it's very close and the 1/2hp will cost a little less to operate so if anything, you may just have to run it for one additional hour per day to compensate. You will be surprised how much water a 1/2hp will move. The only issue with smaller pumps is if you have pop-up cleaner heads or a suction driven automatic cleaner such as a kreepy krauly, however, if a 3/4hp will run it, a 1/2hp will run it as well. You can install a larger motor on the super pump but it will not move more water unless you upgrade the impeller as well. Just make sure you don't use a bigger impeller than what the motor is rated for because it will strain the motor and cause it to overheat. Hope this helps.

While it is always possible the
motor is bad 99 times out of 100 it is a connection issue on-site that leads to
this. Based on your description it is usually a motor set for 230V that is only
getting 115V. It will run if started while "cold' but rather quickly it
will overheat and trip the overload. Once it cools again it will kick back on
however it will run far less time before it shuts off again. This cycle repeats
itself, each time the motor running for a shorter period of time.
Measuring incoming line voltage to ensure it is correct both statically and once under load is the only way to verify the issue is the motor and not the connection or line side of the electrical system. Make sure the voltage selector on the rear of the motor is set to match that incoming line voltage once measured with a meter.
