Since it's a "safety" feature, I didn't expect parts to be cheap but my
vinyl Infinity 4000 pool cover was quoted at 3,000 dollars and the motor
at
1,200 dollars.

It's apparently a 3/4 horsepower motor shown here

1200 dollars seems steep for a 3/4 hp motor, even if it is submersible.

Do you think a "regular" 3/4 hp motor will work in its place?



You are not just buying a motor, but a complete drive system. A submersible
motor and stainless geared system can be quite pricey. While a regular 3/4
hp motor may work, it is subjected to a rather harsh environment and may not
last more than a year or so with the combination of water and chlorine.
They you still need a drive mechanism. If you were to assemble a system of
your own, I can see where you'd spend $500 to $700 for parts easily and they
may not work nearly as well or for long.
