Hi Everyone.. I am kinda new at this and just bought my first Checkmate last June. I didnt realize what I was getting into when I did, LOL!... But I love it and love the boat.. Its a 2000 ZT280 with an original 100 hrs on it with a 502 mag..... I live in Wyoming at high altitude and have a mirage 23 with just barely 4600RPM top speed of 66MPH... Just bought a 22P Bravo 1... I have been recommended to move to this prop for the RPM difference and the all around performance... Anyone have any other thoughts??
