Boat owners with Tohatsu or Mercury outboards, this voltage regulator might be exactly what you need to get your electrical system working properly again! This replacement part fits Tohatsu MFS25 and MFS30 models from 2005-2014, plus Mercury F25 and F30 outboards. The part numbers match 898103T14, 853811T10, and several 3AC-76065 series numbers, so you can cross-reference with your original part. The aluminum heat sink case provides excellent heat dissipation, which is crucial for maintaining proper voltage regulation during extended operation. With output voltage of 14.5±0.5V, this regulator ensures your battery charges correctly and your electrical components get stable power. The wiring comes in various lengths (10cm, 15cm, 25cm) to accommodate different installation setups. If your outboard is having charging issues, dimming lights, or electrical gremlins, a failing voltage regulator is often the culprit. Installation is pretty straightforward as a direct replacement - no modifications needed. The build quality feels solid, and the price is much more reasonable than buying from the dealership. Just make sure your specific outboard model matches the compatibility list before ordering!
