Every boat is different. My son tried a 2'' imco on his 98 Baja 24 outlaw, saw no improvement. I tried it on my 260 prowler. it let be turn a bigger wheel which picked up my cruise by 5 mph. Picked up about 3 mph at wot.

They work much better with higher HP. With stock engine boats it tends to help handling but not speed. It will lower your cruise speed using the same prop as before.
The more HP you have it tends to help more.

Where do you live - I have two.
They have been on a few boats locally.

Tinkerer, what do you have Imco?
Email me at [email protected] I may be interested. I have standard Imcos on my boat and need to try shorties.

Do you have to trim a lot for max speed? If you do the drive will help.

depends if trimming is loosening the prop up or picking the bow and wetted surface on boat up. If your trimming to lossen boat up you may loose bow carrying leverage with a shorter drive. On my 272 Baja I was convinced that my drive was too deep and tried a 2" shorty based on the fact it goes the fastest with lots of trim ( my prop c/l is 7.5 inches BUT don't forget these boats have a pad on the bottom, in my case it hurt top speed and killed the handling of the boat, would barely carry the bow and bow steered like crazy. Put a 1"spacer in and it helped, put stock length drive back on and it was the best, also while testing boat tried to swap ends at mid 90's too from losing bite and I was lucky to not get ejected, sold that shorty!!!!! I also tried a ext box with same crappy results, Smitty
I think maybe over stock speeds but under real high speeds they might help.
