jack shaft with omc?

[ieagreg1]

I'm hoping someone might be able to point me in the right direction. I have a custom designed and built 21' mahogany run about thats using an omc 3.0/cobra I/O. The main problem is the cg is to far back and would like to use a jack shaft to move the engine forward rather than use trim tabs or fuel tank/battery relocation. I have read that mercruiser has this set up availible but have not been able to find any engineering data or contacts. Any help is greatly appritiated.
Thank you

This is one set up.Maybe water ballast up front like race boats use could be easier and more versatile.
