I have a (new to me) 2003 zx225 with a 2007 Yamaha hpdi 250 10" slidemaster manual jackplate. I used the boat about 3 times and spun the hub on my Yamaha 15 5/8 27 M series prop. I was getting 74 out of that prop at 5700rpm. I have tried multiple props to replace this both 27p and 25p that Just blow out without feathering it to get on plane. I'm currently running a a smaller diameter prop that is a 25p. I'm only getting about 60mph out of it at 5900 Rpms. The boat has more throttle, but to stay under 6000 rpm trimmed up this is all I can get out of it. This is the first prop I have found that will get me on plane without blowing out, but I'm slow as Christmas. Any recommendations on where I should go from here would be greatly appreciated! Can't really figure out what prop I need since they don't make these Yamaha props anymore, and that seems to be the best one for this boat to perform like it should. Th aka
