ARCO Marine Premium Replacement Tilt Trim Sender f/Mercury

The ARCO Marine Premium Replacement Tilt Trim Sender for Mercury is an OEM-grade electrical component built to restore precise trim and tilt control on your outboard motor. After years on the water, any angler or boater knows that responsive tilt and trim operation is essential for shallow-water navigation, fuel efficiency, and smooth operation at varying speeds. This sender bridges the gap between your helm control and drive mechanism, converting physical inputs into accurate electronic signals that tell your motor exactly where to position itself.

Engineered to match Mercury factory specifications, this sender works across MC-I, R, MR, Alpha, Alpha Gen II, and Bravo drive platforms—covering decades of Mercury propulsion systems. The compact 4 x 3 x 5 inch form factor and lightweight 0.75 lb design fit seamlessly into existing mounting cavities without modification. The sender uses sealed electrical contacts and corrosion-resistant materials to withstand saltwater spray, humidity, and the constant vibration of prolonged operation—critical durability factors for any marine electrical component exposed to harsh environments.

Boaters experiencing sluggish or non-responsive trim adjustment, or those maintaining aging Mercury engines, will find this replacement sender restores factory-level performance without the cost of a complete drive overhaul. Installation is straightforward for anyone with basic mechanical skill—simply disconnect the original sender and swap in the new unit using standard fasteners. This sender directly replaces Mercury part numbers 805320A03 and 805320A1, ensuring perfect fit and electrical compatibility on your specific drive model and year.
