For racers, owners and professional techs working with Mercury Marine and Mariner outboard motors, the OEM Air Temperature Sensor (Part Numbers: 13221A1, 13221T01) is a critical component to the fuel system to ensure peak engine performance.
This sensor is specifically designed for use in some of Mercury’s and Mariner’s most iconic motors, including Pro Max, ROS, Sport Jet, Super Magnum, S3000, and 300 Drag models and more. By providing the ECU (Electronic Control Unit) with real-time intake air temperature data, it ensures accurate fuel management. This precision is essential for maintaining the perfect air-fuel mixture required for optimal power, efficiency, and reliability.
The sensor fits a wide range of high-performance Mercury Marine and Mariner outboards, including motors such as the 150 HP, 175 HP, and 200 HP, as well as specialized engines like the 250XB EFI, 300X Pro Max, and 200 EFI Super Magnum.
Additionally, it is compatible with legendary models like the 2.4L Laser 220 HP, which is renowned for its unique high-performance characteristics, and the powerful S3000 and 300 Drag motors designed for drag and tunnel boat racing enthusiasts. Whether you’re focused on recreational boating, high-speed applications, or offshore racing, this sensor ensures your engine delivers consistent performance and efficiency.
The OEM Air Temperature Sensor 13221is manufactured to Mercury Marine’s and Mariner’s exacting standards, ensuring precise functionality and seamless compatibility. Its durable construction is built to withstand harsh marine environments, including saltwater corrosion, temperature extremes, and vibration.
Designed for engines that demand precision, like the S3000 and 300 Drag, this sensor provides the ECU with the critical data needed to make real-time adjustments to the air-fuel mixture. The result is optimal fuel efficiency, maximum power output, and reduced emissions.
When an air temperature sensor fails, it can lead to poor engine performance, increased fuel consumption, and potential long-term damage due to improper air-fuel mixtures. By replacing it with the genuine OEM Air Temperature Sensor (P/N 13221A1, 13221T01), you restore proper ECU functionality and maintain the reliability of your Mercury Marine or Mariner outboard.
This sensor is also essential for engines like the 2.4 Laser 220 HP, 225 Pro Max EFI, and 150 EFI Super Magnum, as well as newer models designed for both performance and longevity.
Whether you own a Pro Max, ROS, Sport Jet, or one of Mercury’s racing legends like the S3000 or 300 Drag, the OEM Air Temperature Sensor is designed to meet the needs of your high-performance outboard engine. Its broad compatibility with engines ranging from 150 HP to 300 HP, including the iconic 2.4 Laser 220 HP, makes it an essential part for marine enthusiasts, professional racers, and technicians alike.
Don’t settle for aftermarket alternatives—choose the genuine Mercury part that ensures your engine operates efficiently, reliably, and at peak performance.
