I have a 1995 Malibu Sunsetter lx. I know not the best ski wake option, but the boat fits our family needs perfectly. Looking to upgrade from the stock prop to either the Acme 515 or 525. From my findings there is not a whole lot of difference between the two. I know the 525 is considered high altitude, we live at 3,600ft and frequent a lake at 4,500, but the guy at Acme said I would only see about 150 rpm difference between the two props. My initial thought is to get the 525 for our elevation. But have found many people saying that the 515 softened their wake. Will the 525 help with this as well? Hoping since these are fairly old props you guys have had some experience with both and can give me some insight.
