ABSTRACT:
A water ski line retractor which comprises a reverse polarity motor which functions a drive pulley through a worm gear drive. The drive pulley is connected by a belt to a spool pulley which is loosely mounted upon a shaft. A line winding spool fixedly mounts upon the same shaft in side by side juxtaposition to the spool pulley and a clutch is interposed between the line spool and the spool pulley in a manner to permit relative movement of the line spool and the spool pulley. A two way switch controls motor operation in clockwise and counterclockwise direction for automatic line extending the line retrieving purposes.
