Abstract
A boat steering assembly (10) having a substantially circular rotary gear (12) engaging an output gear such that the leverage is varied between the output gear (16, 16') and the steering wheel (32). The steering wheel (32) has a shaft gear (28) engaging in idler gear (22) which eccentrically rotates the circular gear (12) about the first axis (14). The eccentrically rotating circular gear (12) engages the output gear (16, 16') having a partially sinusoidal profile thereby automatically varying the distance (i.e., leverage) between the first axis (14) and a point of contact (52) between the circular (12) and output (16, 16') gears.
