A marine engine has a crankshaft that rotates about a crankshaft axis; a crankcase supporting the crankshaft, the crankcase being made primarily of a first material; and a cover on the crankcase. The cover includes a heat exchanger having an inner plate facing an interior of the crankcase, and the inner plate is located such that rotation of the crankshaft causes lubricant in the crankcase to impinge upon the inner plate. The cover also includes a frame holding the heat exchanger and isolating the heat exchanger from direct contact with the crankcase. At least a portion of the frame is made of a second material that is more compliant than the first material.
