So I have been thinking about this for a while, I know I should post this in the props section and will also but thought it might get a little more play here. So what dictates which prop you need? how does one know if the boat needs a stern lifter or a bow lifter? I know what the difference means but is it more of a step hull thing VS a deep 24* straight bottom thing. I understand that step hulls like to run flat and most have pad bottoms to go with it, whereas a stright bottom 24 * deadrise boat usually has no pad to ride on and needs to carry the bow to reduce wetted surface. All of the step boats I see these days are running higher X dim and 5 bladed wheels. I have a twin step Donzi 27 ZX with a 500 EFI/ Bravo one drive with a 2 inch shorty that I keep thinking needs the bow lift so I have a Bravo I prop with some rake and aditional cup put in it to carry the bow. Performance is good but I have never run a stern lifting prop on the boat per say and am wondering if a stern lifter would help it ride higher in the water and more on the pad.......an anyone shed some light on this subject? JUst some thought on my part.....

i have the same boat stepped and supercharged.imco 2" and spinning a bravo 30 with a cut flare ring.the boats fast but runs low on the nose and takes of into little hop tangants at certain speeds and now is a little worst with the new shorty.certain weight aboard and the perfect conditions the thing will lift up and take off up to almost 90.on a normal day 83.i believe get that bow up regardless of stepped hulls or not.if the bow is down your going to go slower.singles,twins or 50 foot turbines.Get the bow up.now how do we find a prop that will lift the bow with out slowing us down.how did your rake labbing change the charictoristics of the boat.did it get your bow up and speed you up?.did bblades do it for you?im starting to flirt with the standoff box idea personaly.
