My 17 has a Slidemaster 8″ plate on it.Id talk to BCB and see what they recommend. The “regular” Sabre back then was rated for a 175, so I cant imagine why they would say you couldnt put an 8″ on. The new catalog says they come with a Detwiler plate, but mine came with a Slidemaster. Dont know whats up with that.At any rate, BCB jackplates have 6 holes instead of 4, so Id get it from BCB, unless manufacturers offer the 6 bolt version.2017 Sabre FTD AE DC2017 Yamaha 175 SHOMK Fortrex 80Helix 10 Mega SI in consoleHelix 7 GPS SI GN2 on bow
