Abstract

An electrical component housing for the powerhead of an outboard motor in which the housing is mounted to the engine between oppositely slanted cylinder banks, which provide a V-shaped engine. The engine is mounted to an adaptor plate, and the electrical component housing is interconnected with the adaptor plate through projections provided on the housing which are received within recesses formed in the adaptor plate. Mounting flanges are provided at the upper portion of the electrical component housing, and are secured in mounting surfaces associated with the engine.
