Anyone use the Anchormate ll ??I installed one last year on my 14' Jon.Put the crank at the rear so I don't have to go up front to drop an anchor and bow mounted the piece the anchor gets pulled up into.I use a 15# river anchor and it is supposed to be rated for 18#.It did seem to be pushing it with the 15# anchor.It worked ok last year and now this spring it is slipping when cranking it up.Anyone have issues with this?
