Acme 2160

Just changed from my original 14x16 OJ 3 blade (that was rebuilt) to an Acme 4 blade 2160 13.5 x 13.75. For my normal use seems like a great upgrade - strong hole shot and most of our usage is between 12 to 33 MPH - My son said "Dad you don't have to gun it - its launching me out of the water"    Of course over the last few days my Protec system is showing its age and on its last legs and can't get the boat over 2300 RPM without miss firing. Will update later but initial impressions are very good. '93 SNOB 351W 285HP 1.23 trans.
