Hydraulic Trim Tabs with One-Button Integrated Helm Control
The Bennett 219-129OBI is a complete hydraulic trim tab system built around the OBI9000H — a single-button integrated helm control that simplifies trim tab operation to a single rocker switch at the helm. Designed for boaters who want the power and precision of hydraulic actuation without the complexity of a multi-switch panel, the OBI system automatically levels the tabs when you release the switch, making trim adjustments fast and intuitive.
The 12" x 9" blade size is well-suited to mid-size powerboats, and the full hydraulic drivetrain delivers consistent, load-bearing performance in rough water and at higher speeds. Everything required for a complete installation is included in the box.

Parts Desk Insights
Best Use Case: Recommend the 219-129OBI to customers who want hydraulic trim tab performance but prefer a simplified, single-button control experience at the helm. The OBI system is a strong sell for boaters who find multi-switch panels confusing or who are upgrading from a basic electric tab setup. The automatic tab-leveling on release is a key differentiator — lead with that feature. The 12" x 9" blade is appropriate for mid-size powerboats in the 20–26 ft range; for larger or heavier hulls, recommend the 18" x 12" Euro-Style system instead. If the customer wants fully automatic, sensor-driven control, upsell to the Autotrim Pro for Hydraulic Tabs. Always confirm transom material and boat length before finalizing the recommendation.
