    Spartan Motor and water

    If motor (stock) have been under water, do I need to open it and let it dry? (freshwater)
    If I do, how do I do it? I see screws back of motor and front.

    When I have opened it should I just let it dry or use some WD-40?

    You have to remove the tray, then unscrew the motor from the tray. The motor end cap that faces the rear of the boat can be removed with 3 screws. You will likely find the motor is full of water. I know mine was. I blew it out with compressed air at a low setting and then let it dry over-night. When reassembling, I oiled the bearings.

    I agree with drying the motor out . If it is a stock castle motor then the bearings are sealed. This is from Castle tech support.

    You can also spray the inside of the motor with WD40 to help displace water. Leaving the motor "wet" with WD40 is OK, just drain any excess WD40 before re-assembly.

    I flooded my lipos many times and have never had a problem. Oh just a quick quiz for everyone what does WD40 stand for?

    Instead of wd40 etc which is a great tip, and compressed air. I have used a hair dryer on a low setting a few times to blow hot air through motor to displace and evaporate moisture. Any comments on that welcome.
