Engineered Marine Products 1300-03777 Throttle Position Sensor for Marine V6 V8 Engines

The Engineered Marine Products 1300-03777 is a high-quality replacement throttle position sensor (TPS) designed for marine inboard and sterndrive engines. This critical sensor monitors the position of the throttle valve and sends voltage signals to the engine control module (ECM), allowing for precise fuel delivery and ignition timing adjustments.

Key Features:

• Three-wire sensor design for accurate position monitoring
• Engineered to meet or exceed OEM specifications for reliable performance
• Direct replacement for Volvo Penta, MerCruiser, and other marine engine brands
• Compatible with V6 and V8 marine engines including 4.3L, 5.0L, 5.7L, 6.2L, 7.4L, and 8.1L applications
• Helps restore engine power and fuel efficiency when original sensor fails

A faulty throttle position sensor can cause poor engine performance, loss of power, rough idling, and reduced fuel economy. This replacement TPS restores proper communication between the throttle and engine computer for smooth, efficient operation. Cross-references with Sierra 18-7700 and multiple OEM part numbers including Volvo Penta 3857487, MerCruiser 802623/853678/8M0097035, and others.
