just get the ACME puller kit. I got one last year after wrecking 2 props.There's no way I'm taking the boat out if the acme case (with a spare prop inside) isn't in the boat. like the other guys said, all you need is a pair of gloves and a 12'' 2X4 to lock the prop in place while you undo the nut. the kit comes with a big wrench, pliers(I think) extra cotter pins. I call it the weekend saver
