The E-Gear was developed and introduced by Aqua Marine Supply in the early 2000's.  It was the first of its kind for the boat lift industry.  The E-Gear takes the maintenance out of the equation with a double reduction gear set that is fully enclosed in a cast-aluminum housing.  Although small improvements have been made in the way of seals, bearings, etc, the E-Gear is still in production today; in increasingly higher numbers every year.  When properly applied and inspected, the E-Gear will get the job done with virtually no maintenance required.
