**first of all take out the motor from sea water by isolating it from the connections and take it to the electrical workshop.
—now measure the insulation resistance which will be very low up to 200 ohm so the main problem is to restore the insulation resistance and this can be restored by 3 ways. –1.cleaning.
—dismantle it and wash the winding with fresh water and clean the grease or oil on the windings with the help of using a depressant liquid such as Arma clean.
—now dry the stator winding with the help of heaters or cargo cluster(lamps) with plenty of ventilation to allow the dampness to escape.
—same thing for rotors and bearings.cleaning can be done with high speed diesel oil.
—now assemble the motor and turn the motor for some revolutions for checking tightness and all
—Go for insulation resistance test(IR TEST),asif it remains high over a few hrs. Apply a couple of coats of good quality air -drying Insulating varnish.
- -Now load the motor with the pump by taking
