Description

How to Match This Part

This aftermarket 3-wire trim position sender replaces Volvo Penta 21484383 (supersedes 3841840). It reports sterndrive trim angle to the helm gauge on Volvo Penta SX-A, DPS-A, DPS-B, and TSK applications that call for this OEM number.

Match this part in this order:
1. OEM number on the sender you are removing or in your parts catalog (21484383 or superseded 3841840)
2. Drive / transom family — Volvo Penta SX-A, DPS-A, DPS-B, or TSK calling for that number
3. Wire count — this listing is the 3-wire contact-style trim sender (not a later non-contact trim-sender kit)

Confirm the connector and mounting layout against the product images and your original unit before ordering. Trim senders can share a similar housing while serving different drive generations or wiring layouts, so the OEM number and drive family matter more than appearance alone.

Part Number Cross-Reference

Part numbers are listed for identification only. This is an aftermarket part manufactured by JLM Marine and is not sold as a genuine Volvo Penta component.

Compatible Sterndrive Models

Confirm your drive or transom shield model on the identification plate and that the removed sender is numbered 21484383 or 3841840. Review Volvo Penta diagrams when available: Parts Diagrams.

Brand Application Notes
Volvo Penta SX-A sterndrive 3-wire trim position sender when OEM calls for 21484383 / 3841840
Volvo Penta DPS-A / DPS-B sterndrive Same 3-wire sender application family
Volvo Penta TSK transom / trim system (including TSK-A with SX-A) Match by OEM number and wiring layout; later non-contact kits differ

Important: Do not order from drive family alone if your catalog or removed part shows a different number (for example a later non-contact trim-sender kit). This listing is for the 3-wire contact-style sender 21484383 / 3841840 only.

Installation Guide

1

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

2

Remove the retaining hardware that secures the sender. 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 fully, then refit the retaining hardware to the original torque practice for your drive.

4

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

5

Reconnect the battery. Cycle the drive through full down and full up and verify the helm trim gauge tracks smoothly. Recheck for water intrusion at the mount after the first sea trial.

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

Troubleshooting & FAQ

Is this an OEM or aftermarket part?+

This is an aftermarket JLM Marine replacement matched to Volvo Penta 21484383 / 3841840. It is not a genuine Volvo Penta part.

How do I confirm this fits my drive?+

Check the identification plate for SX-A, DPS-A, DPS-B, or TSK, then match the number on the sender you are removing to 21484383 or 3841840. If your catalog calls for a different trim-sender kit number, do not order this listing.

What symptoms point to a failed trim sender?+

Common signs include an erratic or stuck trim gauge, no gauge movement when trimming, or a gauge that no longer tracks drive angle. Inspect wiring and grounds before replacing the sender.

Does this fit older OMC Cobra 2-wire trim senders?+

No. This listing is the Volvo Penta 3-wire sender 21484383 / 3841840 for SX-A, DPS-A, DPS-B, and TSK applications. Older OMC Cobra 2-wire senders use a different part family.
