The trim gauge functions similar to the sender in the gas tank. It displays the trim and the tilt angle of the outboard motor. Provides details on the engine position relative to the boat stern and identifies proper adjustment of the trim tabs. The trim levels are vital in preventing damage to the propeller especially when crossing shallow waters. It features a white perimeter-lighted dial with stylish bluish graphics, a black contoured pointer in a domed glass lens, and a 2-inch gauge requiring a 53-millimeter or 2.062 inches mounting hole. Best fits Johnson Evinrude and Suzuki Outboard.
