How to Match This Part

This aftermarket 3-wire trim sender sensor replaces Volvo Penta 21652399 (also listed as 3858212). It reports sterndrive trim angle to the helm on Volvo Penta SX applications that use digital European gauges.

Match this part in this order:
1. OEM number on the sender you are removing or in your parts catalog (21652399 or 3858212)
2. Gauge type — digital European trim gauges (not analog or US-style gauges)
3. Drive / TSK code — Volvo Penta SX sterndrive TSK codes listed below that call for this number

Confirm the connector and mounting layout against the product images and your original unit. The OEM number and gauge type matter more than appearance alone.

Installation Guide

1

Disconnect the battery. Locate the existing trim sender on the sterndrive or TSK assembly and note wire routing before unplugging.

2

Remove the retaining hardware. Withdraw the old unit carefully so the mounting bore and any sealing grommet are not damaged.

3

Install the new sender in the same orientation. Seat any grommet or seal, then refit the retaining hardware using the original practice for your drive.

4

Reconnect the 3-wire harness. Confirm the connector is fully seated and that wires stay clear of moving trim linkage.

5

Reconnect the battery. Cycle the drive through full down and full up and verify the digital helm gauge tracks smoothly. Follow the Volvo Penta service procedure for your drive if calibration is required.

Note: Professional installation is recommended to ensure safety and optimal performance.
