Couple weeks ago when I went to check out a boat, the guy had pieces of plastic that he would use to take some of the weight off the hydraulics.<br /><br />He raised it all the way, slipped the plastic pieces over the shiny part of the hydraulics and then lowered them a little until the plastic inserts had some weight on them.<br /><br />Is this common? Anyone know where to buy something similar? Is it necessary?
