73.6 gps! I have an 07 P4 w/ an 07 200 hpdi. This past weekend a friend had a 24 Fury and suggested I try it. I was very impressed to say the least! I was running a 25m yamaha and i ran 69-70 and was satisfied. I tried a 25 Fury last year and it ran about the same as my 25m. I sort of wrote the whole prop thing off and felt comfortable that I had a solid running P4 and I was pretty well maxed out performance wise. The 24 Furys performance was literally unbelievable. Holeshot is marginally better but midrange and top end are so much better that I had to make several runs to believe it! Inner plate on the slidemaster is 1/4″ above flush and im running 5900-6000 rpms. Im not really a speed freak as ive always felt like I should spend that money on fishing and fishing equipment, but I do want my boat to run to its potential and I believe that it now is. The only reason im posting this is to let other P4 owners and potential P4 owners know that, contrary to popular belief, these boats can be pretty quick for their class!
