extension box
 

well, our 16 year old bravos are holding up, but we figure it would be a good idea to replace em this winter so we dont suffer any more time away from water. we have triple 600hp 625 torque now with stock bravos, showers, and nose cones. first off, the revolution hull is already known for porpoising, and when u get three big blocks back there it makes it wrose. are the nose cones magnifying the effect of raising the drives and making it porpoise worse? would extension boxes help the porpoising or make the porpoising worse? i am lookin at the imcos, would u want the stock boxes or ones with the 3 inch lift? also, does anyone have any feedback on how the arneson rocker plates helped porpoising? thanks

my experience for the most part, has shown to increase porpoising. how ever changing the x does help, either 3" lift or by using shorties. either way for the most part they have increased speed.

so raising the drives reduces porpoising?
