A cylinder liner with improved cooling and strength is disclosed. The cylinder liner includes a liner wall extending annularly about a piston bore. The liner wall has an inner face adjacent the piston bore and an outer face oppositely arranged relative to the inner face. The outer face includes a water jacket surface that is co-extensive with at least part of the outer face. A plurality of indentations are disposed along the water jacket surface of the liner wall. The plurality of indentations extend radially inwardly from the water jacket surface to define corresponding areas in the liner wall of compacted material. Accordingly, the plurality of indentations increase surface area of the water jacket surface to improve heat transfer away from the liner wall while also increasing hoop strength of the liner wall.
