A marine engine comprises a cylinder block that defines a cylinder bore; a piston that reciprocates in the cylinder bore under force of combustion in the marine engine; and a liner disposed in the cylinder bore between the piston and the cylinder block. The liner provides a running surface for the piston. The liner has a cylindrical liner body that is sized to fit snugly within the cylinder bore and a pair of diametrically opposing tabs axially extends from liner body into the cylinder bore. Methods of making a marine engine are also disclosed.
