5001298 Evinrude Johnson Exhaust Pressure Sensor Nipple Fitting | Genuine OEM BRP Outboard Part

🔧 Product Description

Genuine BRP Evinrude Exhaust Back-Pressure Sensor Nipple - Part Number: 5001298

A genuine BRP exhaust-pressure fitting used on selected Evinrude direct-injection and E-TEC outboards.

This is not a general-purpose hose fitting. The nipple threads into the exhaust adapter, cylinder block or crankcase assembly and connects to the exhaust back-pressure sensing hose. The EMM uses the pressure signal as part of its engine-load and combustion-control strategy.

⚙️ Key Features

• Genuine BRP exhaust back-pressure nipple
• Correct OEM reference 5001298
• Designed for direct-injection and E-TEC engines
• Connects the exhaust-pressure passage to the sensor hose
• Precision orifice must remain clean and unrestricted

🚤 Compatibility

Commonly used on

• Evinrude Ficht direct-injection engines
• Evinrude E-TEC 60-degree V4 and V6 engines
• Exhaust-pressure sensing systems connected to the EMM

Typically suits

• Engine models:
• Evinrude E-TEC 115HP - selected 2007-2012 engines
• Evinrude E-TEC 130HP - selected 2009-2012 engines
• Evinrude E-TEC 150HP - selected 2007-2012 engines
• Evinrude E-TEC 175HP - selected 2007-2012 engines
• Evinrude 200HP direct-injection and E-TEC applications
• Selected 2.6L 60-degree V6 models
• Engines whose cylinder-and-crankcase diagram specifies 5001298
• HP Range: Primarily 115HP - 200HP
• Engine Type: V4 or 60-degree V6 direct-injection two-stroke outboard
• Year Range: Approximately 2000-2012, dependent on engine family

🔌 Function

The nipple transfers exhaust pressure through a calibrated passage and hose to the engine-management system. The resulting pressure signal helps the EMM determine operating load and adjust engine control.

⚠️ Common Signs of Failure

• Exhaust-pressure diagnostic fault
• Engine hesitates or runs poorly under load
• Carbon blocks the nipple orifice
• Pressure hose repeatedly comes loose
• Corrosion damages the threaded fitting
• Engine-control readings become erratic
• Nipple breaks during removal
• Exhaust residue accumulates inside the sensing hose
