Yamaha Marine Systems (Bennett) 6BT500847900 Trim Tab Actuator Assembly Small

The Yamaha Marine Systems Company (Bennett) 6BT500847900 is a small/short hydraulic trim tab actuator assembly, manufactured by Bennett Marine — a division of Yamaha Marine Systems Company. This is the direct OEM-equivalent replacement actuator designed for Bennett hydraulic trim tab systems.

Bennett hydraulic actuators feature a strong yet flexible nylon/fiberglass cylinder construction that delivers reliable, maintenance-free performance in harsh marine environments. The piston-style arm extends to push the trim tab into the desired position with precision and authority. Hydraulic fluid is routed through a concealed fitting in the upper hinge at the top of the actuator body, completely eliminating external hoses that are vulnerable to chafing, UV degradation, and impact damage.

Key Features:

• Short/small form factor — designed for applications where a compact actuator is required
• Nylon/fiberglass cylinder construction for strength and corrosion resistance
• 2.5" standard stroke for consistent tab travel
• No external hoses — hydraulics route internally through concealed transom fitting
• Maintenance-free design built for long-term marine use
• OEM Yamaha part number: 6BT-50084-79-00 (also referenced as 6BT500847900)
• Backed by Bennett Marine's industry-leading support

This actuator assembly is a genuine Bennett Marine component sold under the Yamaha Marine Systems Company brand. It is an ideal direct replacement for worn or damaged short actuators on compatible Bennett hydraulic trim tab systems.
