Steve,
Congrats on the 143 mph. We have talked many times at loto. I have the 25 Daytona with the ilmor. I run in the c1f1 class.
If I send you my imco lower can you profile and add a tq tab to it? My steering crabs over 90mph.
Your pm box is full

I deleted everything out of my PM box but it must have to reset. I still can't PM. Give me a shout at the shop and we can discuss your lower. (205) 672-8763

I remember playing w/props on my first 100 MPH boat. Like most, I was only after WFO #'s.
I ran from 22's to 32's and validated what a really smart guy once told me."The rig will want what it want's and more pitch doesn't necessarily mean more speed".
Ended up, 3 MPH's covered from the 26 to 32 but the 26 was an absolute blast to drive!
Most have no idea.
I never lost a race in that boat when going from a 30/40 roll and taught me a great lesson.
I like your thinking

Give me the small wheel anyday...besides that, the days where I can String the Kryptonite out to 90 on our busy lake are few and far between...,.put a short poke into the 80s is easy

Skeg
IMCO added a leading edge extension to the skeg and blueprinted the lower. Then we massaged the skeg in order to reduce the torque steer and avoid prop "blow out". With a cleaver style prop, the torque steer causes the drive to run cocked in the water which blows a hole in the water through cavitation. This hole will cause the prop to blow out. The work that IMCO did only helps the situation and is really for twin style applications. It does not do anything to help with the torque steer. We reshape the skeg to get it to hydrodynamically pull on the left side of the skeg to get it to run true in the water. We normally build a torque tab onto the skeg to push the drive straight. By reshaping the skeg, we are able to use the water to pull the skeg straight which creates less drag.
