Default Turbocharging a Marine Engine

Has anyone tried turbocharging a 5.0 L or 5.7 L Merc engine in this
group? I know that it used to be done back in the 70's but I can't
find any info about any current set-ups. From what I can find it
seems like it might be advantageous by allowing you to run a better
pitch prop for higher top end speed and reduced RPMs for cruising
which seem like it would be good for efficiency and engine life. I
don't think it would drop your low end that much because the
compression on stock marine engines is close to 9:1 and you can
probably run 10PSI of boost on 8.5:1 engines. Any thoughts or
comments? I am more familiar with turbo applications on cars so I
might be missing something. Thanks for the help!
