    Patent number: 11499499
    Abstract: A marine engine has a cylinder block defining at least one cylinder bore and a cylinder liner providing a running surface for a piston in the cylinder bore. The cylinder liner is non-axisymmetric relative to a center axis of the cylinder liner. The cylinder block defines a pocket that retains the cylinder liner and prevents the cylinder liner from rotating about the center axis. Novel cylinder liners, assemblies and methods are provided for forming a marine engine having the cylinder block with the cylinder liner formed therein.
