Volvo Penta trim sensor sending unit 3 wire SX DP is a drive-side trim sender used on select Volvo Penta sterndrive applications.

Key Features
- Genuine Volvo Penta trim sensor / trim sending unit application
- 3-wire sender design
- Used for trim-position signal on select SX and DP sterndrive systems
- Supports proper trim gauge and trim-position indication
- Best matched by exact drive model and serial number
Engine Compatibility
This part should be matched by drive and transom assembly, not by engine long-block alone. Based on the description provided, it is associated with select Volvo Penta SX and DP sterndrive applications using a 3-wire trim sender setup. Because Volvo Penta used multiple trim sender styles across different drive generations, the safest fitment path is to confirm the exact drive model, transom assembly, and serial-number-based application before ordering.
Serial Number Fitment Notice
Match this trim sensor sending unit to your drive serial number and the correct Volvo Penta trim-system diagram before ordering. Trim senders can look very similar while using different wiring layouts, connector styles, or calibration ranges.
When This Part Needs Replacement
This sender is commonly replaced when trim indication becomes inaccurate, the trim gauge stops responding correctly, the sender housing is damaged, wiring is corroded, or the trim signal becomes intermittent during operation. It is also worth checking anytime the transom shield or trim-related wiring is already apart.
Installation Notes
Confirm the original sender is a 3-wire version before installation, and compare the removed unit carefully against the replacement part. Check the connector style, wire length, mounting position, and harness routing before reassembly. On Volvo Penta trim systems, exact application matters more than a visual guess.
Alternate/Superseded Part Numbers
Because the exact OEM number was not included in this line, the safest approach is to match this part by:
- OEM part number
- 3-wire configuration
- SX / DP drive application
- serial-number-based parts diagram
Parts Desk Insight
With trim senders, the easy mistake is matching only by appearance. On Volvo Penta SX and DP systems, checking whether the sender is 2-wire or 3-wire first usually saves the most time and helps avoid ordering the wrong unit.
