0328821 0127466 OMC Trim Tab | Genuine Used Part

🔧 Product Description

Genuine OMC Johnson / Evinrude Torque-Compensating Trim Tab - Current Part Number: 0127466

A genuine OMC adjustable trim tab fitted behind the propeller on selected Johnson and Evinrude gearcases. The tab offsets propeller steering torque and also protects the gearcase as a sacrificial corrosion component on applicable installations. Current service number 0127466 replaces earlier 0328821.

⚙️ Key Features

• Genuine OMC adjustable trim tab
• Current service number 0127466
• Supersedes 0328821
• Corrects steering torque on standard-rotation gearcases
• Gearcase-mounted marine aluminium component

🚤 Compatibility

• Johnson / Evinrude 35HP-55HP gearcases where the 127466 tab is specified
• Johnson / Evinrude 60HP, 70HP, 75HP, 85HP, 90HP and 100HP applications
• Selected larger OMC gearcases using the same tab profile
• Approximate service-family era: late 1970s through 1990s
• Standard-rotation installations; counter-rotation torque correction differs
• Exact fitment depends on gearcase casting and trim-tab bolt location

🔌 Function

The adjustable tab produces a small hydrodynamic force that counteracts propeller steering torque and helps the boat track with reduced helm effort.

⚠️ Common Signs of Failure

• Tab is missing or broken
• Steering pulls strongly to one side
• Adjustment marks are lost
• Mounting bolt is seized
• Tab is heavily corroded
• Propeller contacts an incorrectly positioned tab
