Hydraulic Trim Tabs with One-Button Integrated Helm Control — 18" x 9"
The Bennett 219-189OBI is a complete hydraulic trim tab system that pairs an 18" wide blade with a 9" chord — a configuration that delivers strong lateral lift across a wide transom while keeping the blade profile lower than a full 18" x 12" setup. The OBI9000H one-button integrated helm control keeps operation intuitive: a single rocker switch at the helm, with automatic tab leveling when you release.
Hydraulic actuation provides the power and precision to handle variable loads, rough water, and higher speeds. Everything required for a complete installation is included in the box.

Parts Desk Insights
Best Use Case: Recommend the 219-189OBI for customers with wider-transom powerboats — typically in the 22–28 ft range — where the 18" blade width is needed for full transom coverage but the 9" chord is sufficient for the hull weight and speed profile. This is a good middle-ground option between the 12" x 9" and the 18" x 12": wider coverage than the 12" blade, but less chord depth than the full 18" x 12" for hulls that don’t need maximum lift. The OBI one-button control is a strong selling point for customers who want simplicity at the helm. For fully automatic hands-free control, upsell to the Autotrim Pro for Hydraulic Tabs. Always confirm transom width, boat length, and hull weight before finalizing the blade size.
