470 to 120 swap

[Rranger]

I have a complete 120hp mercruiser setup prop to front engine pulley installed in a boat now. Have a chance for a better boat with a blown 470. If I completely strip the 470 down to the bare transom will there be any issues besides front motor mounts? Or is there more potential problems? I realize less speed with the 120 but it will get me to where I want to go.

If the donor boat is older than mid 70s the transom cutout is slightly smaller. But very doable if you have 2 complete boats
