The Mercury Idle Air Control Valve recall affects specific models of Mercury outboard engines, particularly those manufactured in 2021. This recall is crucial for boat owners as it addresses potential safety hazards related to engine performance.

Overview of the Recall

The recall involves Mercury Outboard FourStroke engines with horsepower ratings of 75, 90, 100, 115, 135, and 150. These engines may have been fitted with an Idle Air Control Valve (IAC) that does not meet specifications. An out-of-specification IAC can prevent the engine from returning to a slow idle speed after operating at higher speeds. This malfunction could lead to dangerously high engine speeds, complicating the ability to shift gears and increasing the risk of accidents.

Affected Models

The following models are included in the recall:

  • FourStroke 75hp
  • FourStroke 90hp
  • FourStroke 100hp
  • FourStroke 115hp
  • FourStroke 135hp
  • FourStroke 150hp

Serial number ranges for the affected engines are:
  • 75 - 115hp: 3B034165 to 3B084339
  • 135 - 150hp: 3B021624 to 3B067243

Owners of these engines should check their serial numbers against this range to determine if their unit is affected.

Safety Hazards

The primary concern with an out-of-specification IAC is that it may cause the engine to maintain a higher than normal idle speed. This situation can lead to:

  • Difficulty in shifting out of gear
  • Increased risk of loss of control over the boat
  • Potential for accidents and injuries

Important info: If you own an affected engine, it is recommended that you stop using your boat immediately until repairs are made.
