28 thunder set ups
any 28 thunder owners with 500efi what prop are you running at what gps speed and rpm,, been trying all summer to get my buddys 28 dialed in. works best with a left handed 24 4 blade it hit 69 on gps at 5200, im thinking he should be able to spin a 26 labbed. he has a 26 labbed that spins 5000 and only low 60 mph i think it has a bad slippage problem.
thanks
thanks

try this prop slip calculator, it should cut out a lot of guess work

Stock RH 26 Bravo on 2004 or newer 28 with a 525 runs 73-75.
Stock LH 24 Bravo on the 2002 back 28 with a 500 runs 69-71.
Lab finished Merc prop up two pitches and gain 2-3.
Full time mufflers, scrub 5. (don't ask)
