I realize this story is too late to change the OP's mind and it is about a Drive Saver, not an Aqua Drive, but here goes anyway:
Years ago I bought a really nice J/32 sailboat. The engine vibrated at higher rpms, so I got a price adjustment to deal with that. It had a folding prop and a Drive Saver.
I wanted to replace the folding prop with a Max Prop as part of the solution to the vibration problem. The yard doing the work said to get rid of the Drive Saver. It wasn't doing any good they said and when it was installed the PO didn't shorten the shaft to make up for the Drive Saver. The prop was extending beyond the 1-1/2 diameter rule of thumb and may have been causing the vibration. I said ok.
It turned out great. Smooth as silk. All I could figure out was that the PO installed the Drive Saver to reduce vibration. Turns out that the vibration was caused by a bent prop. The bolt holding the two halves of the folding prop together had a 1/2" kink in it.
The moral of the story: get your drive train right and you don't need a kludge.
