Continuing the Miami theme, Livorsi Marine is unveiling its new billet trim tabs at the 2015 edition of the Miami International Boat Show. The company will be offering four versions of the tabs, the 750 Performance, 850 Military, 950 Mercury Replacement and 1050 Performance. All Livorsi tabs are CNC- machined from billet aluminum and feature mil-spec hard-coat anodization to resist corrosion. Owners can choose between Livorsi's LED electronic position indicators or mechanical indicators that use 33C cables. Hinge pins and hardware are stainless steel, and you can adjust transom angles without the use of special tools. The hydraulic cylinders are designed for 1,500 psi working pressure and the tabs have four sacrificial anodes so they are protected against corrosion.
