Engineered Marine Products 93-04000 Zinc Trim Tab Anode for Mercury MerCruiser

The Engineered Marine Products 93-04000 is a high-quality zinc trim tab anode designed to provide essential corrosion protection for marine stern drive and outboard motor gearcases. This sacrificial anode protects valuable metal components from galvanic corrosion in saltwater and freshwater environments by attracting corrosive elements away from critical drive parts.

Key Features:

• Constructed from high-grade zinc material for superior corrosion protection
• Direct replacement for Mercury OEM part numbers 31640Q4, 316404, 31640B4, 31640A4, 316403, 31640A1, 72436A1, 31640, and 31640A2
• Compatible with most Mercury/Mariner outboards 35hp and above
• Fits MerCruiser 1 Drive, EZ Shift, MC-1, MC II/TR/TRS, R/MR/Alpha One, Alpha One-SS, Alpha Gen II, and SSM gearcases
• Fits all MerCruiser stern drives except Bravo models
• Interchangeable with CMP, Honda Outboard, and Tecnoseal equivalent anodes
