Yamaha Bennett EIC Trim Tab Relay Module 12V – 6BT-50024-27-00

The Yamaha 6BT-50024-27-00 is a genuine Yamaha OEM EIC relay module used with select Yamaha/Bennett Electronic Indicator Control trim tab systems. This 12-volt control module is part of the trim tab electrical system, helping route helm control inputs, tab position feedback, and auto-retract functions through the EIC trim tab control setup.

This module is not an engine-mounted outboard part. It is a rigging/accessory electrical component used in compatible Bennett-style trim tab installations where the Yamaha rigging diagram or Bennett EIC system documentation calls for this module.

Key Features

• Genuine Yamaha OEM trim tab electrical control module.
• Yamaha part number supplied: 6BT-50024-27-00.
• Alternate formatting: 6BT-50024-27 and 6BT500242700.
• Supplied alternate prefix reference: 68T-50024-27-00 verify exact prefix by Yamaha rigging diagram before ordering.
• Associated Bennett system reference: EIC101 verify by system layout before substitution.
• 12-volt DC trim tab control module.
• Used with compatible Electronic Indicator Control trim tab systems.
• Supports helm switch command routing and trim tab position indicator wiring where specified.
• Used with compatible auto tab retractor-style trim tab installations where the system wiring supports that function.

System Compatibility

Common application context includes select Yamaha rigging and Bennett-style trim tab systems by installation diagram, module part number, helm control, and wiring harness layout, including:

• Select Yamaha/Bennett Electronic Indicator Control trim tab systems where specified.
• Select 12V Bennett EIC trim tab installations using a rear-mounted relay/control module.
• Systems using a compatible helm-mounted EIC control/display.
• Trim tab installations with compatible position indication wiring and tab retraction wiring.
• Stern or transom-area installations where the factory rigging diagram calls for 6BT-50024-27-00 or the verified matching module number.

Use this module only where the Yamaha rigging/accessory diagram or Bennett EIC system documentation specifically calls for this part.

Fitment Notice

Confirm fitment by boat rigging diagram, Yamaha accessory part number, Bennett trim tab system model, helm control/display part number, hydraulic power unit wiring, actuator/sensor wiring, and existing module label before ordering. Trim tab systems can use similar-looking relays, rocker switches, indicator controls, harnesses, and control modules that are not interchangeable.

Before publishing or ordering, verify whether the correct Yamaha prefix is 6BT or 68T for the exact installation.

When This Part Needs Replacement

Replace this module if the trim tabs do not respond correctly after confirming power, ground, helm switch input, actuator wiring, hydraulic power unit function, fuse/breaker condition, and harness continuity. It should also be inspected if the tab position indicators stop tracking, the auto-retract function fails, the module casing is cracked, connectors are corroded, or the wiring shows water intrusion or heat damage.

Installation Notes

Mount the module in the dryest practical stern or rigging location, above normal bilge water level and away from direct spray whenever possible. Keep wiring supported, strain-relieved, and routed away from sharp edges, battery terminals, fuel components, and moving steering or trim hardware.

Do not splice shielded or low-voltage signal wiring unless the system manufacturer’s service instructions specifically allow it. Poor splices, corroded connectors, weak grounds, and voltage drop can create false position readings or intermittent trim tab operation. Confirm the ignition-switched feed is connected correctly if the installation uses auto tab retraction.

Alternate/Superseded Part Numbers

• 6BT-50024-27-00 Yamaha OEM part number supplied
• 6BT-50024-27 alternate catalog formatting
• 6BT500242700 condensed catalog formatting
• 68T-50024-27-00 supplied alternate prefix reference; verify by Yamaha rigging diagram
• Bennett EIC101 associated Bennett EIC module reference; verify by trim tab system before substitution
• 6BT-50024-23-00 related helm/display reference supplied; verify by system diagram

Parts Desk Insight

Trim tab control modules should be diagnosed as part of the full electrical system, not replaced blindly. A bad ground, weak battery feed, corroded connector, failed helm control, actuator problem, or hydraulic power unit issue can mimic a failed relay module. Matching the module by the label on the existing unit and the Yamaha/Bennett wiring diagram helps avoid ordering the wrong EIC component.
