Sierra 18-1523 Trim Assembly Relay, Replaces 61A-81950-01, Fits Yamaha 60-250 HP Outboards

The Sierra 18-1523 Trim Assembly Relay is a direct replacement electrical relay for the power trim and tilt system on a wide range of Yamaha outboard motors. This relay is the component that switches power to the trim motor, allowing the operator to raise and lower the outboard's tilt angle from the helm. When a trim relay fails or corrodes, the outboard can lose the ability to trim up or down, or the trim motor may run continuously or not at all, so replacing the relay restores normal, controlled trim operation.

This relay uses a plug-in connector for a straightforward, tool-minimal installation and mounts using a DIN rail mount configuration, consistent with the factory relay layout used in Yamaha's trim system wiring harness. Internally it uses copper contacts for reliable current conduction and consistent switching performance, and it is built to meet OEM specification so it operates as a like-for-like swap for the original relay. Sierra backs this part with its standard customer satisfaction warranty.

The 18-1523 fits a broad range of Yamaha outboard horsepower and model designations, including F25, T25, 60, 70, 75, 80, 85, 90, 150, 200, 225, and 250 HP models across the specific model years listed below, making it a common service and maintenance replacement part for Yamaha outboard trim systems.
