Two speed pump comparison

[DavidP77]

My above ground pool pump keeps over heating and kicking out. I am not sure what is causing this and if anyone does please let me know what the cause might be. It run 24 hours a day 3 1/2 months a year and is 8 years old. I am looking at a possible replacement of either a Pentair two speed 1 HP 340204 or a Hayward Matrix 1 HP 2 SPEED ABOVE GROUND PUMP PMP HAY SP15922S . I am not sure how the two compare nor am I sure how you switch from low to high. Does anyone run these motors and if so how do you switch from low to high? I only have 110 running out to my filter/pump so I don't have the option of 220. If anyone has either of these pumps or know which would be the better pump please let me know. I currently have a 1.5 HP Hayward Power Flo LX with a 200 lb. filter. I am reading I need to switch to the 1 HP to not over drive my filter and to get a two speed to save both money on my electric bill and to get the pool cleaned more efficiently on the low speed.
