Well we ran the boat today. Just over 5000 with 34's. Not good only 92. Took forever to get on plane too. Some testing and fine tuning and it will be close! Motors make 725. With the whipples.

What year, what lowers?

hmm curious what boat?
what are you planing on spining the motors up to?
mine had to spin 5750 to get 106 with big 5 blade herrings. thats with 700 hp motors. blue printed bottom 2 in short sportmaster lowers with 1 in spacers so wuld get on plane better,
have fun
be carefull!!

He must have a 1.5 gear ratio to. Mine has a 1.36 with wipples.

stock xr lowers. 2004 35 lightning 725hp whipple motors WRONG PROPS!! Took 30 sec to get on plane. 50-80 4.2sec

high 90's of now.

That should be a 105-107 mph boat...

Really?? We are spinning 34's to the 525 rev limiters now...

Hey Jonas,

Did you notice a difference when you had your hull blueprinted - or did you do it along with other modifications so you really couldn't tell? I was considering having mine done this winter.

i wish i could tell you, but i cant,, it was done when i got the boat,
but i do have a pretty good comparison due to my neighbor has exact same boat same yr, power etc but bone stock.
his is much squirlier,
at 75 ish his starts dancing mine never did that like that,
i think due to the rocker they put in it takes a better set,
sorry this is all speculation,,
but in comparison my boat was just alot more stable and much faster,
wishi could be more help.
