Engineered Marine Products 300-01404 Marine Voltage Rectifier for Mercury Outboard Engines

The Engineered Marine Products 300-01404 is a marine voltage rectifier designed for Mercury and Mariner outboard engines. This essential electrical component converts alternating current (AC) from the stator into direct current (DC) to charge the battery and power onboard electrical systems.

Key Features:

• Rectifies AC power output from the alternator charging generator (ACG)
• Charges and maintains fixed battery voltages to prevent overcharging
• Provides overheat protection with efficient heat sink design
• Helps dissipate excess voltage to protect electrical components
• Direct replacement for Mercury OEM part numbers 62351A1, 62351A2, and 816770
• Cross-references to Sierra part number 18-5707

This rectifier is an aftermarket replacement suitable for various Mercury and Mariner outboard models. A properly functioning rectifier ensures reliable starting, bright lighting, and stable electrical system performance. Signs of a failing rectifier include poor starts, dimmed headlights, and fluctuating voltage meter readings.
