How to Match This Part
This aftermarket trim position sensor replaces Mercury / Mariner / Quicksilver 888590002 (and the earlier number 888590). It mounts on the Verado swivel-bracket / cradle area and reports outboard trim angle to the engine controls and instrumentation.
Match this part in this order:
1. Number on the sensor you remove — 888590002 or 888590
2. Engine family — Mercury or Mariner Verado inline-six (6-cylinder) four-stroke outboard, 200–300 HP
3. Serial number on the engine ID plate / midsection bracket against the compatibility notes, then compare the two-hole sensor face and corrugated harness with the product images
Four-cylinder Verado and other outboard families use different sender numbers — confirm the stamped OEM number before ordering.
Part Number Cross-Reference
Use these verified Mercury numbers to confirm you have the correct Verado trim position sensor. Brand names and OEM numbers are for identification only.
| Type | Brand | Part Number | Notes |
|---|---|---|---|
| OEM | Mercury / Mariner / Quicksilver | 888590002 | Current trim position sensor |
| OEM | Mercury / Mariner | 888590 | Earlier number; superseded by 888590002 |
This is an aftermarket part manufactured by JLM Marine. It is not sold as a genuine Mercury Marine, Mariner, or Quicksilver component.
Compatible Engine Models
Confirm your Mercury or Mariner Verado inline-six outboard below. Find the serial number on the engine identification plate / midsection bracket, then use Mercury Parts Diagrams for the mount-cradle sensor callout.
| Brand | Engine Family | Rated HP | Serial / Notes |
|---|---|---|---|
| Mercury / Mariner | Verado 6-cylinder 4-stroke | 200, 225, 250, 275 | Covered OEM where-used blocks include 0P409357–2B144122 family ranges and 1B227000 & Up — confirm your serial on the parts diagram |
| Mercury / Mariner | Verado 6-cylinder 4-stroke | 300 | Covered OEM where-used blocks include 0P520553–2B144122 and 1B517434 & Up — confirm serial before ordering |
Always match the number on the sensor you remove. If your Verado uses a different trim sensor PN (for example later Pro Verado black sensors), this listing is not the correct replacement.

Installation Guide
- 1Turn the ignition off and disconnect the negative battery cable before working on trim wiring or the cradle-mounted sensor.
- 2Trim the outboard fully in (full down). Note connector orientation and harness routing on the old sensor before unplugging it.
- 3Remove the mounting screws and withdraw the old sensor from the mount cradle. Compare the new unit side by side — two-hole face, harness length, and connector should match.
- 4Install the new sensor on the cradle and tighten the fasteners to the torque values in your Mercury / Mariner Verado service manual.
- 5Route the corrugated harness clear of moving parts, mate the connector until it latches, and reconnect the battery.
- 6Power up and verify smooth trim travel from full in to full out. Perform any trim-position adaptation or calibration required by your engine’s service procedure after sensor replacement.
Note: Professional installation is recommended for Verado trim position sensors.
