We need a SPX Stone Part No. 1788*AC 12V, is this one the right choice?
A: This is a 1789-AC. We can find no information directly relating to a 1788 on Stone's website, but suspect it may actually be a KMD-2. We carry the KMD-1 and the KMD-3. They should be interchangeable, as they are all the same motor platform. As long as the shaft, mounting, and wiring is correct it could work.

Is the KMD3 a little longer than the KMD1? Other sites show that the heavy duty motor is 3/4" longer than the normal one. I am looking for a Stone brand part#1789-AC and it needs to be 7 3/4".
A: Yes, the KMD3 measures 7.520" overall (less shaft), while the KMD1 measures 6.940" overall (less shaft).

we have to replace a 4142-AC 12 V motor for our boat hoist. Should / can we substitute for the 1789 - standard or extended motor?
A: We have no information about that motor and cannot state compatibility. Our motors are made by/intended for SPX power units. If the shaft diameter, spline, rotation, and mount pattern matches it may be possible; but that would be your determination to make. The extended duty cycle will allow for 15 more seconds of run time at full load when used with SPX power units.
