The tabs’ hydraulic cylinders are designed with dual seals and 1,500 psi working pressure. The bolt patterns match those used with Mercury K-Planes, and there is a smaller pattern for center-consoles. Livorsi’s 950 tabs are a direct factory replacement for Mercury K-Planes. Transom angles on the Livorsi tabs can be adjusted without needing special tools, so they can be installed on boats where other tabs might not be applicable. Each kit includes two billet tabs, trim pumps, mounting hardware, wire harnesses and through-hull fittings. Stainless-steel braided hoses are available.
