I don't have any direct experience with recovering a submerged electric motor, but I've used similar products. LPS3 seems to be a good rust inhibitor, it sounds a lot like Boeshield T-9 developed by Boeing for the aerospace industry. So for most parts of an electric motor, there shouldn't be an issue and the water displacement properties should be a real benefit against corrosion. I was concerned a little when I considered the brushes and commutator on brushed motors, I would figure that it might impede the motor's normal operation. However, the Boeshield FAQ page stated "Can I safely use T-9® on the inside of my boats distributor cap and rotor also on the male on female pins of electrical plugs which would then be rejoined? You can use our product inside the distributor and on both sides of electrical connectors. Although it is non-conductive, there is enough friction to break through the coating and make contact. It will also help lubricate the connection and keep corrosion out." So as a layman, I don't see a problem with this type of product used on an electric motor. Open frame motors may even be easier to deal with in this scenario than some of the more sealed motors.
Good suggestion, Mark. I'll keep that in mind since I typicaly already have a can of T-9 onboard.
