I converted my inboard 3.0L from a I/O. all that midsection/lower unit/steering crap is heavier than you think. I weighed that crap, and I weighed the strut/rudder/shaft/Velvetdrive also. I was shocked what I found out.

Not sure I follow. You mean you removed the inboard and made a transom for an outboard on the stern? Not really what I have in mind.

No, the other way around.
I bought a donor I/O boat, removed the engine, sold off all the I/O stuff, and made myself a straight inboard.

Some of the 1st generation small jet boats used a power head from an out board. The impeller was run vertical.

I guess my most significant worry is thrust under the center (CG) of the hull. What's wrong with having the thrust that far forward, as opposed to at the stern?

Modern outboards have power trim. How would you get nose dive?
