Abstract
A horizontal shaft electric powerhead includes an electric motor, a battery, a housing, and a base plate. The electric motor includes a horizontal output shaft configured to rotate about a horizontal axis of rotation and has a power rating of 2,500 or fewer watts. The battery includes a plurality of lithium-ion battery cells and is coupled to the electric motor. The housing has a standard cross-sectional footprint so that the electric powerhead has substantially the same volume as a comparable small internal combustion engine. The base plate is configured to be fastened to a mounting surface and includes a plurality of openings arranged in a standard horizontal shaft engine support pattern.
