The Bennett ST12 12x12 Performance Sport Tab Systems come with a single boat indicator control (Model: ST12OBI). These tabs help your boat get on plane quickly and stay there at intermediate speeds. They correct listing and uneven loads, reduce pounding, and eliminate porpoising. They also improve visibility and safety. With low maintenance and long - term value, these tabs are a great choice. The Performance Tabs feature a sophisticated black - powder - coated finish. Made of heavy - gauge reinforced stainless steel and powerful hydraulic actuators, they combine strength, durability, and good looks. What's in the box: (2) Trim plane assemblies, (2 - 4) Hydraulic actuators (A1101ARC), (1) Hydraulic power unit (V351HPU1), hydraulic tubing and hardware, and an OBI9000H One Boat Indicator Control.

Using your Bennett ST12 Sport Trim Tabs is easy. First, make sure all the parts in the box are properly installed according to the included instructions. When you start your boat, the tabs can help it get on plane quickly. At intermediate speeds, keep them in use to maintain stability. If your boat starts to list or has uneven loads, adjust the tabs to correct the balance. This will also reduce pounding and stop porpoising. Remember, improving visibility and safety is one of the key benefits of these tabs, so use them in different boating conditions. As for maintenance, since they have a low - maintenance design, you just need to check the hydraulic system regularly for any leaks. Wipe down the black - powder - coated finish occasionally to keep it looking good. With proper use and care, these tabs will provide long - term value for your boating adventures.
