The Bennett 12x9 BOLT System with Adjustable Upper Hinge gives your boat's transom a properly sized set of trim tabs designed to sharpen handling and efficiency. The BOLT System's adjustable upper hinge allows for precise installation alignment, while the 12-inch span and 9-inch chord deliver meaningful lift to get your hull on plane faster, reduce porpoising, correct a persistent list, and keep your bow at the right angle as speed, load, and sea conditions change. Controls are sold separately.

Sizing Guidelines:

• For boats with top speeds under 40 MPH, use at least 1 inch of tab span per side for every foot of boat length -- a 22-foot boat typically needs a 24x9-inch tab
• For speeds 40 MPH and above, a Performance or Premier Line high-performance system is generally recommended
• Choose the widest span that fits your transom -- greater surface area means greater lift
• A 9-inch chord is standard; shorter or longer chords, upfin, or dropfin shapes may suit certain transom configurations
