How to Match This Part
This aftermarket 3-wire trim sender sensor replaces Volvo Penta 3849411 (also listed as 3849413, 3855535, and 3863007). It reports sterndrive trim angle to the helm on Volvo Penta SX and DP-S / DP-SM applications that use a standard analog trim gauge.
Match this part in this order:
1. OEM number on the sender you are removing or in your parts catalog (3849411, 3849413, 3855535, or 3863007)
2. Gauge type — standard analog trim gauges (not Volvo Penta digital gauges with indicator lights)
3. Drive / TSK code — Volvo Penta SX-M family or DP-S / DP-SM codes listed below that call for this number
4. Wire count — confirm a 3-wire harness; this listing is not the 2-wire trim-sender family
Confirm the connector and mounting layout against the product images and your original unit. The OEM number, gauge type, and wire count matter more than appearance alone.

Installation Guide
1
Disconnect the battery. Locate the existing trim sender on the sterndrive or transom 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 analog helm gauge tracks smoothly. Follow the Volvo Penta service procedure for your drive if sender adjustment is required.
Note: Professional installation is recommended to ensure safety and optimal performance.
