Do NOT cut Seawater Power Cable as it contains live voltage when Seakeeper<\/span><\/span> is in operation. Seakeeper<\/span><\/span> ships with Seawater Power Cable permanently sealed at end of cable with protective cap in the event it is not used. Do NOT remove Seawater Power Cable from Drive Box as moisture will be free to enter box through open cable gland and corrode internal electronic components<\/li>\n<\/ol>\n\n\n\n
