A rotatable shaft is mounted to the raft having a propellor at its lower end located in the upper end of the pipe means with wind driven means to rotate the shaft. The pipe means is pivotable to either a vertical or horizontal position and has means to lock the pipe means in a vertical position whereby the pipe means may be retained in a horizontal position when positioning the raft in a lake or reservoir whereupon the pipe means may be pivoted to a vertical position.
