GOOFIT Marine Series – High-Reliability Outboard Voltage Regulator

Ensure a steady charge on the open water. The GOOFIT 4-Wire Voltage Regulator Rectifier is a premium replacement part designed for 25HP to 70HP outboard engines manufactured between 1984 and 2001. In marine environments, unstable voltage can quickly ruin a battery or damage sensitive electronics. This regulator is engineered to dissipate excess voltage and improve charging capability, providing the stable current your engine needs to run smoothly.

By replacing your aging OEM 6G1-81970-61 unit with this GOOFIT alternative, you effectively prevent battery overcharging and ensure that your engine's electrical system remains balanced. Its compact design and high-grade internal components make it a "fit and forget" solution for seasoned boaters and marine technicians alike.

It is best matched to original part number(s) 6G1-81970-61, 6G1-81970-60, 25HP-70HP. Key physical/spec details from the product data include Mounting Hole: 6mm (0.24") diameter., 25HP, 70HP. Use the compatibility table and product photos together before ordering.

Do I need to match the OEM part number?

Yes. Match your original part number to 6G1-81970-61, 6G1-81970-60, 25HP-70HP before purchase. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type.

What models or situations does this part not fit?

Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. If your original part number does not cross-reference with 6G1-81970-61, 6G1-81970-60, 25HP-70HP, treat the fitment as unconfirmed. Model years outside 1984–2001, 1984, 2001 should be verified separately. Do not rely only on the model name or engine size.

What should I check before ordering?

Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Confirm OEM/cross-reference number(s): 6G1-81970-61, 6G1-81970-60, 25HP-70HP. Recheck listed specs such as Mounting Hole: 6mm (0.24") diameter., 25HP, 70HP. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
