so i have a question? a lot of yall have the acme 1847 but which is better 1847 or the 1617. im wanting to reprop my boat this winter (2011 xlv with 325hp) since i am planing to upgrade balast as well (900 sumo's in back , 1150lb fly high in ski locker and IBS bag upfront maybe) but i cant decide which prop to go with so any help or input would be appreciated.
