Product Details
This aftermarket power trim tilt relay is a replacement relay for selected Mercury and Mariner outboard electrical systems. Catalog information identifies this relay style for use on most Mercury/Mariner 2-stroke and 4-stroke outboard engines, excluding Verado applications. Because marine electrical systems can vary by model, year, serial number, and terminal configuration, compare the original relay and part number before ordering.
The relay is listed as a replacement for Mercury Marine part numbers 882751A1, 882751A2, 828151A1, and 828151. It is sold as one relay, not as a pair.
- Replacement power trim relay for selected Mercury/Mariner outboard applications.
- Designed for use with the corresponding original relay and electrical connections.
- Single-relay package for replacement or service work.
- Aftermarket component; not a genuine Mercury Marine OEM part.
Part Number Matrix
The references below are documented replacement or cross-reference numbers for this relay family. A number match should still be confirmed against the original relay, connector layout, and engine application.
| Brand or Source | Part Number | Reference Type |
|---|---|---|
| Mercury Marine | 882751A1 | OEM reference |
| Mercury Marine | 882751A2 | OEM reference |
| Mercury Marine | 828151A1 | OEM reference |
| Mercury Marine | 828151 | OEM reference |
| Sierra | 18-5849 | Aftermarket replacement reference |
| GLM | 73040 | Catalog cross-reference to 882751A1 |
Engine and Model Compatibility
Catalog evidence describes the corresponding relay as fitting the power trim relay used on most Mercury and Mariner 2-stroke and 4-stroke outboard engines that are not Verado models. This is a broad application description, not confirmation of every horsepower, model year, or serial-number range.
| Brand | Engine Type | Application Scope | Important Condition |
|---|---|---|---|
| Mercury | 2-Stroke outboard | Most applications using the corresponding power trim relay | Verify part number and terminal configuration |
| Mercury | 4-Stroke outboard | Most non-Verado applications using the corresponding power trim relay | Verify model, year, serial number, and original relay |
| Mariner | 2-Stroke outboard | Most applications using the corresponding power trim relay | Verify part number and terminal configuration |
| Mariner | 4-Stroke outboard | Most non-Verado applications using the corresponding power trim relay | Verify model, year, serial number, and original relay |
Not confirmed by the available catalog evidence: a universal 20–300 HP range, all Force applications, or Johnson/Evinrude OMC sterndrive applications. Do not use those descriptions alone to determine fitment. Confirm the exact replacement number and physical configuration before purchase.

Installation Notes
- Disconnect the boat battery at the negative terminal before working on the trim/tilt electrical system.
- Locate the existing trim relay and document the wire or connector positions before removal.
- Compare the replacement relay with the original relay, including the part number, terminal arrangement, mounting features, and connector fit.
- Remove the old relay from its mounting position without damaging the wiring or terminals.
- Install the replacement relay securely in the same position.
- Reconnect each wire or connector to the matching terminal. Do not force a connector or alter the wiring to make it fit.
- Reconnect the battery and test trim operation in both directions in a safe location.
- If the motor operates in only one direction or the relay becomes hot, disconnect power and have the system inspected by a qualified marine technician.
Troubleshooting & FAQ
What symptoms can indicate a faulty trim relay?
Possible symptoms include trim or tilt operation in only one direction, a clicking sound without motor operation, intermittent operation, or no operation. These symptoms can also be caused by a weak battery, damaged wiring, a switch problem, a fuse, or a failed trim motor, so test the complete circuit before replacing parts.
Will this fit my specific engine year or horsepower?
The available catalog description covers most Mercury/Mariner 2-stroke and 4-stroke non-Verado applications using the corresponding relay, but it does not establish every year, horsepower, or serial-number range. Verify the original relay number and physical configuration before ordering.
Is this relay for a Verado engine?
No Verado fitment is confirmed for this listing. The documented application scope specifically identifies non-Verado Mercury/Mariner engines. Use the correct relay reference for Verado models.
Is this a single relay or a pair?
This listing includes one relay. Some trim systems use more than one relay, so check your system before ordering additional components.
Is this an OEM part?
No. This listing is for an aftermarket replacement. The Mercury Marine numbers shown in the part-number matrix are reference numbers only and do not indicate that the replacement is manufactured by Mercury Marine.
Can I use the relay for a Force or OMC sterndrive application?
Those applications are not confirmed by the available evidence for this listing. Do not rely on a general physical resemblance; verify the exact original part number and application with a qualified parts source or marine technician.
Is professional installation recommended?
Yes. Marine electrical systems should be serviced carefully. Professional installation is recommended when the connector layout, wiring, or relay function is uncertain.
Safety & Important Information
- Disconnect the battery before removing or installing the relay.
- Verify the original part number, terminal layout, connector style, and physical appearance before purchase.
- Do not assume that a horsepower range or engine-family description confirms fitment for every model year or serial number.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended for uncertain or damaged marine electrical systems.
