5050

I would like to know hp and speeds GPS on bullets cafes and flat bottom guns. From what i've seen or heard they are all realatively close in how much power to push them.
My bullet ran 71 to 72 in smooth water and 75 in big water when it had 500s and i think clays bullet runs about the same. Mine now has 625, and runs 80.
A friend of mines gun runs 85 with 750s, same guy had a bullet with 725 and it ran 85.

I have heard flat bottom guns and cafes run about 70 to 72mph with 500s is this true?

My bullet ran 83 with approx 625's

My straight-bottom Top Gun ran 109 when it had 1250's in it.

hmm, i really need to get my speedo fixed this summer. if u are doing 68 w/ 425hp, i should be able to hit low 70s w/ my 525-550hp.

Our Kevlar Gun with SC600s always ran low 80s and with 850's ran low to mid 90s.

A lot had to do with the props. Got the boat it had three blades Mercury ran 64 mph then I put on 4 bladded Labbed Spinelli's and it kicked up to 68.

I cannot recall pitch and so forth but I think it was in the 24" range, I could be wrong, it was a while back.

Maybe if you search Cafe Props and so forth you might find older posts with all that information.

90 Cafe.

Fresh 502's with Small Weiand Blowers, all Roller Drivetrain, 850 Nickerson Carbs, Bravo's, 4 Blade 26's

I "THINK" I am in the 575 hp range, and the fastest I have seen yet was in some decently rough water - 72mph. Of course this was chock FULL of FUEL and everything for my wife and I to stay two nights - (clothes, coolers, ice, liquor, soda, dock chairs in the nose etc...).

I think that someone who knew what the hell they were doing could squeeze a couple more mph out of it.... My wallet precludes me from running it hard!!
