Hydraulic Trim Tabs with One-Button Integrated Helm Control — 12" x 12"
The Bennett 219-1212OBI is a complete hydraulic trim tab system featuring a square 12" x 12" blade — a configuration that delivers more chord depth than the standard 12" x 9", making it well-suited to mid-size powerboats that carry heavier loads or need more lift authority without stepping up to a full 18" wide blade. The OBI9000H one-button integrated helm control keeps operation simple: 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 219-1212OBI when a customer has a mid-size powerboat — typically 20–26 ft — that is running heavier loads (full fuel, gear, passengers) and the 12" x 9" blade isn’t generating enough lift to trim the hull effectively. The square 12" x 12" blade is the right step up before moving to an 18" wide system: same transom footprint width, more chord depth for added lift. It’s a good recommendation for customers who feel their current tabs are “working but not quite enough.” 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 and boat weight before finalizing the blade size.
