880886T 881441T4 881441T3 Mercury Manifold & Throttle Bodies | Genuine Used Part

🔧 Product Description

Genuine Mercury Mariner 115 EFI Intake Manifold and Throttle Body Assembly - Part Number: 880886T / 881441T4 / 881441T3

A genuine used Mercury Mariner intake-manifold and throttle-body assembly for Yamaha-derived 115HP EFI four-stroke outboards.

The assembly combines intake manifold 880886T with the applicable throttle-body version from the 881441 family. Different throttle-body revisions were used across the serial range, so the installed connector, control valve and serial break must be matched.

⚙️ Key Features

• Genuine Mercury Marine OEM intake components
• Includes manifold 880886T and an 881441-series throttle body
• Used on Yamaha-derived Mercury / Mariner 115 EFI four-strokes
• 881441T4 is identified on early applications through serial 0T408999
• Includes mounting locations for idle-control, pressure and throttle-position components

🚤 Compatibility

Commonly used on

• Mercury and Mariner 115 EFI four-stroke intake systems
• Yamaha-derived 1.7L inline four-cylinder Mercury four-stroke outboards

Typically suits

• Engine models:
• Mercury / Mariner 115 EFI four-stroke - serial 0T178500 to 0T800999

• Engine Type: Mercury / Mariner Yamaha-derived inline four-cylinder EFI four-stroke outboard
• Year Range: Approximately 2001 - 2006

🔌 Function

The manifold distributes intake air to the cylinders, while the throttle body meters airflow according to control input. The attached sensors and idle-control passages allow the engine-control module to manage fuel delivery, ignition and idle speed.

⚠️ Common Signs of Failure

• Throttle plates stick or linkage binds
• Manifold gasket or shaft leakage causes an unmetered-air leak
• Idle-control passages become contaminated
• Throttle-position or manifold-pressure signal is incorrect
• Engine idles poorly, hesitates or cannot reach full RPM

🔄 Supersession & Cross Reference

OEM Supersession Chain

• 881441T3 → Supersedes 881441T1
• 881441T1 earlier throttle-body reference
• 881441T4 alternate early-production throttle-body version
