Troubleshooting & FAQ

Q: How do I confirm this switch fits my specific engine?

A: First, confirm your engine is a Mercury or Mariner model from 1999 or newer, between 25-400 HP. Next, and most importantly, check the part number on your remote control box itself to ensure it matches one of the compatible models listed, such as 881170A15 or 881170A20. Verifying the control box part number is the most reliable method.

Q: What are the common signs of a failing tilt and trim switch?

A: Common symptoms include an intermittent or completely unresponsive trim/tilt system when the switch is pressed, the motor only trimming in one direction, or a switch that feels physically loose, stuck, or broken.

Q: Is this a direct plug-and-play installation?

A: Yes, this switch is designed for a direct-fit, plug-and-play installation. It features an OEM-specification electrical connector that matches the harness in compatible Mercury remote control boxes, requiring no cutting or splicing of wires.
