Product Details
This aftermarket Remote Control Tilt/Trim Switch is intended for compatible Mercury and Mariner remote control units. It is designed to provide control of the outboard power tilt and trim system when the original remote-control switch requires replacement.
This replacement is listed for Mercury part numbers 87-18286A43, 87-16991A1, 87-18286A2, and 87-18286A26. Because remote-control switch fitment depends on the control-box design and connector, compare your original switch and control-box part number before ordering.
- Designed as a direct replacement for compatible remote control installations.
- Uses an OEM-specification style electrical connector for compatible applications.
- Black ABS-plastic housing for marine control-box use.
- Aftermarket replacement component; not manufactured by Mercury.

Engine & Model Compatibility
This switch is intended for compatible Mercury and Mariner outboards using the matching remote control assembly. The switch itself is selected by remote-control-box design and connector configuration, not by horsepower alone.

Treat that range as an application guide only and verify the specific remote control before installation.

Troubleshooting & FAQ
How do I know if this switch fits my remote control?
Match your original switch, connector and remote-control-box part number with the references listed above. The application guide includes Mercury and Mariner outboards from approximately 25–400 HP and approximately 1999 onward, but the control-box configuration determines the actual fit.
What are the signs of a failing tilt/trim switch?
Common symptoms include intermittent operation, operation in only one direction, or no response. Before replacing the switch, inspect the fuse, relay, battery and electrical connections for corrosion or damage.
My new switch is not working. What should I check?
Confirm that the connector is fully seated and that the battery and ignition are on. Check the tilt/trim fuse and relay, and verify that the connector and switch configuration match the original. A fault in the trim motor, relay or wiring can produce similar symptoms.
Is this an OEM switch?
No. This listing is for an aftermarket replacement intended for the listed Mercury and Mariner applications. Mercury part numbers are provided as replacement references only.
How quickly is it shipped?
Typical standard transit is 5–15 days. Available shipping methods, delivery estimates and any expedited options are shown at checkout.
What warranty and return coverage applies?
The switch is covered by a 1-year warranty against manufacturing defects under normal use, subject to the seller’s warranty terms. Returns are subject to the applicable return policy and condition requirements.
