when I called the factory about my 1994 31ss they told me that if I raised the X by 2" it would be good for 3mph+ the X on the newer riggs are allready that high, the Imco 2 inch shorty's would be the way to go......and new 4 blade props...

The Hydromotives have a 4 blade semi cleaver look. The mirage just look like plain old props

Great madcow, that is just the answer I am looking for. I'll switch my order to Hydromotives then!

I have to look at my boat sitting on a cradle and want the props to look just as cool as the rest of the boat! <gg>

Looks dont mean anything if they dont work for your application....u cant see the props as the boats going by you!!!if you leave your boat in the cradle full time then whatever...blows your hair back. I'd call the factory and ask wich prop works best for your boat....my .02

Of course, dyno. Your prop suggestion makes perfect sense. That is why I am going to do the opposite. Remember I own a boat and lost my sanity long ago.

I high dry the boat and like to look at the coolest props (like my old ballistics) in cradle row. If I lose one or two mph at max throttle compared to other props, perhaps the raised X will and lab finish will compensate.

Kooky ehh!

Good to know about the 2 inch X speed gain. I decided on one inch up, did they estimate how much this would gain?
