Mercury Marine / Mercruiser OEM Sender Assy-Trim, 8M0083577

Brand new, genuine Mercury Mercury Marine / Mercruiser OEM Sender Assy-Trim, 8M0083577. This is a factory original equipment item, not aftermarket.

This OEM trim sender assembly is a critical component that converts the mechanical movement of the outboard or sterndrive trim mechanism into an electrical signal for the onboard display or control system. It’s precision-engineered at Mercury Marine facilities to meet stringent factory tolerances—guaranteeing repeatable accuracy and reliability. Constructed with a sealed, corrosion-resistant housing, this unit is designed for the challenging marine environment, withstanding moisture, vibration, and salt exposure. Ideal for both replacements and full rebuilds, it supersedes the older part number 863187A04 and integrates seamlessly with Mercury’s SmartCraft and analog gauge systems.

• OEM-quality precision sender calibrated to factory specs
• Sealed design with marine-grade conductor wires and connector for reliable signal transmission
