replace hayward motor on model c48d31a04 serial 10208fm

This model has died. It worked well for long time. Inground pool, small, like 10 x 20 ft… small, there is a pic, maybe you can get some idea by the comparing theone man ladder on the back left. I believe I can just change out the motor… home is a rental… I need replacement at the lowest price, but smart. Stay with Hayward? another brand? will it fit? 1 hp enough, there is a roof solar heater?

thanks
