I just purchased a 2003 388 Slingshot with 575's bravo XR drives 2" imco shorties and boxes. The prop's that are on the boat are 30 pitch bravo's. (not lab finished)

Any other suggestions. Not sure what to expect out of the props on there now.

Thanks,
Chris

30 bravo one 4 blade is what came stock on the 500efi boats with a 1.5 gear,I would think maybe 32's but you have a higher rev limiter in it also.See if it will turn 5400 with the 30's first.Sounds like a good package.Post some picks when ya get a chance,

Thanks for the info.
I will post some pics soon.

Got a couple sets of props sitting at Performance Boat Brokerage at LOTO for sale. They were ran on our 388 with boxes and imco scs. 34 bravos cut down in diameter. only test time, not enough prop for 700 hp. 31 hydro p5xs, very low hours on them, both sets are labbed. feel free to call Jim at 217-482-5738.
