Yamaha Marine Systems Company (Bennett) 6BT500843500 Hydraulic Trim Tab Actuator Assembly

The Yamaha Marine Systems Company (Bennett) 6BT500843500 is a complete hydraulic trim tab actuator assembly, engineered as an OEM-grade replacement for Bennett hydraulic trim tab systems. This self-contained hydraulic cylinder delivers reliable, responsive trim adjustment to help optimize vessel performance, fuel efficiency, and on-plane stability.

Key Features:

• Complete hydraulic cylinder assembly — fully pre-assembled and factory-sealed, ready for direct installation
• Durable plastic resin body — corrosion-resistant construction built to handle harsh saltwater and offshore marine environments
• Nylon upper hinge — designed to flex approximately 5° during operation, accommodating natural tab movement under load
• Concealed internal fluid passage — hydraulic fluid routes through a hidden channel in the upper hinge, eliminating exposed external hoses that are vulnerable to damage
• 2.5" standard stroke — consistent actuation force to push trim tabs firmly into position
• Maintenance-free design — built for long-term reliability with minimal upkeep
• Compatible with Bennett standard hydraulic trim tab systems — not compatible with electric or BOLT trim tab systems

This actuator assembly is the correct OEM replacement part for Yamaha Marine outboard and sterndrive applications that utilize Bennett-manufactured hydraulic trim tab systems. Cross-reference Yamaha OEM part number 6BT-500843500 when sourcing this component.
