Engineered Marine Products 1300-13601 Marine Throttle Position Sensor

The Engineered Marine Products 1300-13601 is a direct-replacement throttle position sensor (TPS) engineered specifically for marine inboard and sterndrive applications. The throttle position sensor monitors the angle of the throttle plate and relays that data to the engine control module (ECM), enabling precise fuel delivery, smooth acceleration, and proper ignition timing across all RPM ranges.

Built to withstand the demanding marine environment, this EMP sensor is designed to restore accurate throttle response and eliminate symptoms such as rough idle, hesitation, surging, or poor fuel economy that result from a failing OEM sensor.

Key Features:

• Direct OEM replacement — no modifications required for installation
• Restores proper throttle signal to the engine control module (ECM)
• Resolves symptoms including rough idle, hesitation, and poor fuel economy
• Marine-grade construction for long-term durability in harsh on-water conditions
• Manufactured by Engineered Marine Products (EMP), a dedicated marine engine parts specialist
