This invention relates to new and useful im

More speci?cally, the invention relates to
power control systems such as power boat con
trol systems which include a motor throttle and
a reverse gear. The invention contemplates the

A new and improved power control system in
accordance with this invention, includes a motor
throttle ill operated by a control lever H, and a
reverse gear I2.‘ Further details of the power

motion of the control member 48, and will remain
in this condition until the control member 48 is
moved back to its neutral position.
