How to Match This Part
This aftermarket trim / tilt position sender kit (potentiometer type) replaces Volvo Penta 873531 and the superseding kit number 22314183 (also listed as earlier number 828726). It reports sterndrive trim and tilt position to the helm gauge on Volvo Penta 290, SP, and DP transom-shield applications that call for these OEM numbers.
Match this part in this order:
1. OEM number on the sender you are removing or in your parts catalog (873531, 22314183, 828726, or OMC/Bombardier 0873531 / 0828726)
2. Drive family — Volvo Penta 290, SP, or DP sterndrive calling for that number
3. Wire configuration — this listing is the 3-wire potentiometer trim-sensor kit (not the 2-wire OMC Cobra sender family for 3850470 / 984748)
Confirm connector style and mounting layout against the product images and your original unit before ordering. If your diagram calls for a different trim-sender number, do not use this listing.

Installation Guide
1
Disconnect the battery. With the boat safely supported, trim the drive to a position that gives clear access to the trim sender on the transom shield.
2
Unplug the old sender at its connector inside the boat, note lead routing, then release the mounting hardware and withdraw the old unit.
3
Compare the old and new units side by side against the product images. Connector style and mounting layout must match before you continue.
4
Install the new sender in the same orientation, seat the mount squarely, and tighten the hardware evenly without over-torquing.
5
Route the lead along the original path, keep it clear of moving linkage and hot surfaces, then reconnect the plug fully.
6
Reconnect the battery. Run the drive fully down and fully up and confirm the helm trim gauge tracks smoothly across its range.
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 873531 / 22314183 / 828726 (and OMC/Bombardier 0873531 / 0828726). It is not a genuine Volvo Penta or OMC part.
How do I confirm this fits my drive?+
Match the number on the sender you are removing to 873531, 22314183, 828726, 0873531, or 0828726, and confirm a Volvo Penta 290, SP, or DP application. If your catalog calls for a different trim-sender 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 the connector, grounds, and lead routing before replacing the sender.
Does this fit the 2-wire OMC Cobra sender (3850470 / 984748)?+
No. That is a different 2-wire sender family. This listing is the 3-wire Volvo Penta trim-sensor kit for 873531 / 22314183 applications on 290, SP, and DP drives.
