I'm running a (new to me) 2003 skeeter zx 225 with a 2007 Yamaha Hpdi 250. When I got the boat it had a Yamaha m series 14 5/8 x 27 prop. It spun the hub on my second outing. I have tried a Solas 14 1/8 x 27 and a Mercury 27p with blowouts when trying to get on plane. Even tried moving the jackplate around with no luck. I'm running a 25p prop on it now but I'm only getting like 60mph @ 5900rpm. With the 25p prop trimmed up, I am not able to get all the motor has out of the throttle without going over 6000rmp. With the 27p that spun the hub I was running 74 at 5700 rpm's. Not really sure where I should go from here, since I have been unable to find the same m series Yamaha prop I was running. Any help or ideas would be greatly appreciated.
