My Donzi 26zx had a 502 carb engine 415hp.....factory says this engine has a max rpm of 5200rpm.....
i hit 4900rpm @ wot with a 4bladed Bravo 1 24p prop.....
im gonna install a 600hp engine, that on the dyno its max hp comes out at 5500rpm.....
my question is, would i need to a bigger prop ? since i need to increase about 600rpm to get to the 5500rpm of the new engine....
i know this all depends on trial and error, but any experiences and info would be appreciated...
thanks
