30" x 9" Recommended Boat Length for 25' to 30'. Kits are complete with planes, transom mount hinges, hydraulic power unit, thru-transom actuators, hydraulic hose and wiring harness but does not include switch. Bennett trim tabs are two independent, stainless steel adjustable afterplanes attached to the bottom edge of the transom. Maximum efficiency is obtained by using the longest span tabs possible. Measure transom from centerline to chine or turn of the bilge allowing 3-4" leeway. Outdrive or outboard applications require minimum 8" clearance from lower unit to tab.
