Abstract
An outboard motor adapter plate couples a marine engine to a driveshaft housing, and includes an upper rim configured to be coupled to a lower surface of a cylinder block of the engine. A lower rim of the adapter plate is configured to be coupled to an upper surface of a sump located in the driveshaft housing. A wall defines a passageway having an inner perimetral surface, and the inner perimetral surface extends from the upper rim to the lower rim. A mounting area is configured for coupling a mount to the adapter plate. A shield covers at least a portion of the inner perimetral surface adjacent the mounting area, so as to at least partially thermally isolate the mount from heated fluid that drains from the cylinder block, through the passageway, and into the sump. A method and a shield for thermal isolation are also described.
