Common failures & inspection points
Examine oil color and consistency by removing oil drain plug; milky white oil indicates seal failure; oil must be changed every 12 months or 6,000 hours (whichever comes first)
Visually inspect galvanic anode for erosion patterns and thickness reduction; replacement is mandatory every 2 years in seawater service; loss of anode protection causes corrosion spread to shaft
Inspect entire external surface for peeling, chips, cracks, or exposed metal; 3-layer epoxy resin coating (minimum 180 microns) must be intact; any bare spots require immediate remediation
Visually examine shaft for surface discoloration, pitting marks, or linear stress cracks; check fasteners for tightness and corrosion; verify anti-wicking cable jacket integrity for moisture barriers
Verify motor protector operation; test megohm resistance between phases and ground; inspect cable connectors for salt crystallization or oxidation; check motor housing drain holes for blockage
