Product Details

The Quicksilver 805226A1 Throttle Position Sensor (TPS) Kit is a genuine OEM replacement sensor assembly designed for MerCruiser stern drive and inboard engines equipped with electronic fuel injection (EFI). The throttle position sensor monitors the precise position of the throttle butterfly valve, relaying critical data to the engine control module to optimize fuel delivery, ignition timing, and overall engine performance.

Key Features:

  • Genuine OEM Quicksilver/Mercury Marine factory part — not aftermarket
  • Direct-fit replacement throttle position sensor (TPS) assembly
  • Compatible with MerCruiser MCM/MIE GM V-6 and V-8 (305, 350, 454, and 502 CID) EFI engines
  • Mounts on the throttle body butterfly spindle for direct throttle position monitoring
  • Backed by Mercury Marine's 1-year factory warranty against defects in materials and workmanship
  • Cross-references: Volvo Penta 3855184; Sierra 18-7630; GLM 9-33701

Replacing a faulty TPS restores proper throttle response, eliminates rough idle or hesitation, and ensures the ECM receives accurate input for precise fuel and ignition control. This is a direct OEM replacement that installs in 1 to 2 hours, making it an accessible repair for experienced boaters or a marine technician.
