How to Match This Part

This aftermarket throttle position sensor (TPS) replaces Mercury MerCruiser / Quicksilver 805226A1. It mounts on the throttle body and reports throttle-shaft angle to the ECM so fuel delivery and spark timing stay coordinated on EFI sterndrive and inboard engines.

Match this part in this order:
1. OEM number on the removed sensor — 805226A1 (also commonly cross-matched to Sierra 18-7630)
2. Engine family — MerCruiser MCM / MIE GM V-6 and V-8 EFI (305, 350, 454, and 502 CID)
3. Physical form — black molded housing, two-hole mounting flange, and a three-terminal electrical connector

Compare the flange holes, rotor/drive slot, and connector shape with the product images before ordering. If your original sensor carries a different OEM number or a different connector layout, do not use this part — other MerCruiser TPS numbers (for example later Mag / Black Scorpion sensors) are separate listings.

Part Number Cross-Reference

Use these verified numbers to confirm you have the correct throttle position sensor. Brand names and OEM numbers are for identification only.

Type Brand Part Number Notes
OEM Mercury MerCruiser / Quicksilver 805226A1 Primary reference (SENSOR KIT-TPS)
OEM Volvo Penta / OMC Stern Drive 3855184 Interchange OEM number for the same TPS family
OEM Crusader 47032 Interchange OEM number
OEM PleasureCraft R020040 Interchange OEM number
Aftermarket Sierra Marine 18-7630 Direct cross-reference
Aftermarket Mallory Marine 9-33701 Direct cross-reference
Aftermarket CDI Electronics E13-0007 Direct cross-reference

This is an aftermarket part manufactured by JLM Marine. It is not sold as a genuine Mercury, MerCruiser, Quicksilver, Volvo Penta, OMC, Crusader, or PleasureCraft component.

Compatible Engine Models

Confirm your MerCruiser model before ordering. Serial location guide: Mercury Parts Diagrams. Always match the OEM number and physical form of the sensor you remove.

Technical Specifications

Specification Value
Part type Throttle Position Sensor (TPS)
Primary OEM replaced Mercury MerCruiser / Quicksilver 805226A1
Mounting Bolt-on throttle-body mount with two-hole flange
Connector Three-terminal electrical connector (plug-in to the existing engine harness)
Housing form Black molded body with keyed throttle-shaft coupling
Engine systems MerCruiser MCM / MIE GM V-6 & V-8 EFI (305 / 350 / 454 / 502 CID)

Installation Guide

  1. 1 Disconnect the battery negative cable and let the engine cool. Remove the flame arrestor if it blocks access to the throttle body.
  2. 2 Release the locking tab and unplug the three-terminal harness from the old sensor. Note how the connector is routed so the new lead is not strained against the throttle linkage.
  3. 3 Remove the two mounting screws and lift the sensor off the throttle shaft. Compare the old and new units side by side: flange holes, shaft coupling, and connector position must match.
  4. 4 Align the new sensor coupling with the throttle shaft, seat it fully against the throttle body, then fit the screws and tighten evenly to the torque in your MerCruiser service manual. Reuse the original screws unless they are corroded or damaged.
  5. 5 Reconnect the harness until the lock clicks, refit the flame arrestor, and reconnect the battery. If your service manual specifies a TPS voltage check or idle reset, follow that procedure with a digital multimeter or the manufacturer diagnostic tool.
  6. 6 Start the engine, let it idle, and open and close the throttle slowly while checking for smooth response and no stored fault codes.

Note: Professional installation is recommended for EFI throttle-body sensors.

Troubleshooting & FAQ

How do I confirm this fits my MerCruiser? +

Read the number on your existing sensor first. If it is 805226A1 (or a verified cross such as Sierra 18-7630), this is the correct replacement for MerCruiser MCM / MIE GM V-6 and V-8 (305, 350, 454, 502) EFI applications. Compare the flange and three-terminal connector with the product images.

Will this fit a MerCruiser 350 Mag or Black Scorpion with a different TPS number? +

No. Sensors stamped 803148 / 8M0230659 (and similar later Mag / Black Scorpion applications) are a different MerCruiser TPS family. Order the listing that matches the number on your removed sensor.

What symptoms point to a failing throttle position sensor? +

Common signs include rough or hunting idle, hesitation when the throttle opens, poor throttle response, and engine fault codes related to throttle position. Confirm the fault by testing before replacing the sensor — wiring and connector problems can produce the same symptoms.

Is this an OEM or aftermarket part? +

This is an aftermarket replacement manufactured by JLM Marine. It is not a genuine Mercury, MerCruiser, or Quicksilver part. OEM and aftermarket numbers are listed only for cross-matching.
